This adds two new options WITH_ASAN/WITH_UBSAN that can be set to

to get a complete buildworld with sanitizer instrumentation but in
order to actually build and boot a system it depends on a few more

Add the ability to link programs against a compat ABI.

Linkage is controlled by two make knobs:
WANT_COMPAT - Prefer to link against the compat ABI.
NEED_COMPAT - Link against the compat ABI or fail to build.

Supported values are "32", "soft", and "any". The latter meaning pick
the first[0] supported compat ABI.

This can be used to provide test binaries for compat ABIs or to link
ABI-specific programs.

[0] We currently support only one compat ABI at a time, but this may
change in the future and some code in this commit is structured to ease
that change.

Created static libc PIC/no-SSP library to be used by rtld.

Rtld is not compatible with SSP, and since we link libc_pic.a to rtld
to have the basic support like memory and string copy functions, we
have to both carefully limit libc use, and to provide the ssp support
shims. This change makes the libc use in rtld more straighforward but
still limited, and allows to remove the shims, to be done in the next

Add limited sandbox capability to "make check"

== Rationale ==

r295380 introduced "make check" and consolidated means for running
test code in an attempt to simplify running tests. One could either
install files/libraries/programs and run "make check", or run "make check"
with an explicit CHECKDIR, e.g., `make check CHECKDIR=$(make -V.OBJDIR)``.

One criticism that was received is that "make check" should be run with
the intent of making dev->test->commit easier, which means that the target
audience's workflow should be developers. One developer pattern available
in other opensource projects is to run test code from a developer sandbox,
instead of installing to a system.

== Method ==

This approach is slightly different from the standard approach, in the sense
that it builds and installs into a deterministic directory under .OBJDIR (as I call it,
the "sandbox"), then runs "make check" against that. In the event the test
run is successful, the deterministic directory is removed to save space.

== Approach ==

bsd.lib.mk, bsd.prog.mk:

To support this functionality, a new variable `HAS_TESTS` is being added.

HAS_TESTS enables appropriate behavior with bsd.lib.mk and bsd.prog.mk, as
follows:
- Add "make check" as an available target from the directory.
- Pass down appropriate variables via ${TESTS_ENV}, i.e.,
${TESTS_LD_LIBRARY_PATH} and ${TESTS_PATH}.

One should add "HAS_TESTS" to directories containing tests in them, e.g. from
bin/sh/Makefile,

HAS_TESTS=
SUBDIR.${MK_TESTS}+= tests

HAS_TESTS doesn't automatically add the tests subdirectory for flexibility
reasons.

bsd.opts.mk, src.opts.mk:
- The knob ${MK_MAKE_CHECK_USE_SANDBOX} has been added, both to explicitly
direct (internally) when to set a deterministic ${DESTDIR} and to also allow
users to disable this behavior globally, i.e., via src.conf.
- MK_TESTS has been promoted from src.opts.mk to bsd.opts.mk to leverage
syntactic sugar for having MK_TESTS be a dependency for
MK_MAKE_CHECK_USE_SANDBOX, but to also ensure that src.opts.mk isn't required
to use suite.test.mk (which is a dependency of bsd.test.mk).

suite.test.mk:
- beforecheck behavior (when MK_MAKE_CHECK_USE_SANDBOX is enabled) is modified
from a no-op to:
-- Build.
-- Run "make hierarchy" on the sandbox dir.
-- Install the tests/files to the sandbox dir.
- aftercheck behavior (when MK_MAKE_CHECK_USE_SANDBOX is enabled) is modified
from a no-op to:
-- Remove the sandbox dir.

Again, because the dependency order set in bsd.test.mk is
beforecheck -> check -> aftercheck, "make check" will not be run unless
"beforecheck" completes successfully, and "aftercheck" will not be run unless
"beforecheck" and "check" complete successfully.

== Caveats ==

- This target must either be run with MK_INSTALL_AS_USER or as root. Otherwise
it will fail when running "make install" as the default user/group for many
makefiles when calling INSTALL is root/wheel.
- This target must be run from a suitable top-level directory. For example,
running tests from `tests/sys/fs/tmpfs` won't work, but `tests/sys/fs` will,
because `tests/sys/fs/tmpfs` relies on files installed by `tests/sys/fs`.
- Running MK_INSTALL_AS_USER may introduce determinism issues. However, using
it could identify deficiences in tests in terms of needing to be run as
root, which are not properly articulated in the test requirements.
- The doesn't negate the need for running "make installworld" and
"make checkworld", etc. Again, this just is intended to simplify the
dev->test->commit workflow.

== Cleanup done ==
- CHECKDIR is removed; one can use "MK_MAKE_CHECK_USE_SANDBOX=no" to enable
"legacy" (r295380) behavior.

Simplify running the FreeBSD test suite

Replace `make regress` (legacy test make target) and `make test` (incomplete
test make target added with the FreeBSD test suite) with make check as it's
consistent with other open source projects.

`make check` defaults to running tests from `.OBJDIR`, but can be overridden
with the `CHECKDIR` variable.

Add `make checkworld` target to simplify running the FreeBSD test suite from
`TESTSBASE` (i.e. the top-level tests directory), similar to buildworld.

Document `make check` and `make checkworld` in build(7).

Other minor changes:

- Rename intermediate file (`Kyuafile.auto`) to `Kyuafile` to simplify
`make check`.
- Remove terse warnings attached to `beforetest`/`aftertest`.
- Add kyua binary check to check target in suite.test.mk; error out if it's
not found

The MFC is [partly] contingent on other build related changes being MFCed.
