MFC r244236,r244408,r244915,r247054,r251512:

Add a new knob WITH_DEBUG_FILES to control the building of standalone
debug files for userland programs and libraries. The "-g" debug flag
is automatically applied when WITH_DEBUG_FILES is set.

The debug files are named ${prog}.debug and ${shlib}.debug for consistency with other systems and documentation. In addition they are
installed under /usr/lib/debug, to simplify the process of installing
them if needed after a crash. Users of bsd.{prog,lib}.mk outside of the
base system place the standalone debug files in a .debug subdirectory.
GDB automatically searches both of these directories for standalone
debug files.

Revert changes that ocassionally got into r241192.

Copy head to stable/9 as part of 9.0-RELEASE release cycle.

Approved by: re (implicit)

Merge binutils 2.17.50 to head. This brings a number of improvements to
x86 CPU support, better support for powerpc64, some new directives, and
many other things. Bump __FreeBSD_version, and add a note to UPDATING.

Thanks to the many people that have helped to test this.

Retire TARGET_ABI.

Implement MACHINE_ARCH=mips64e[lb] to build N64 images. This replaces
MACHINE_ARCH=mipse[lb] TARGET_ABI=n64.

MACHINE_ARCH=mipsn32e[lb] has been added, but currently requires
WITHOUT_CDDL due to atomic issues in libzfs. I've not investigated
this much, but implemented this to preserve as much of the TARGET_ABI
functionality that I could. Since its presence doesn't affect the
working cases, I've kept it in for now.

Added mips64e[lb] to make universe, so more kernels build.

And I think this (finally) closes the curtain on the tbemd tree.

Add missing '/'.

We need to add powerpc64->powerpc translations (I knew I hated copying
this code in the first place).

Also MACHINE_ARCH powerpc is 32-bit, not MACHINE_CPUARCH == powerpc.

Complete the integration of tbemd branch into head.

TARGET_BIG_ENDIAN is now completely dead, except where it was
originally supposed to be used (internally in the toolchain building).

TARGET_ARCH has changed in three cases:
(1) Little endian mips has changed to mipsel.
(2) Big endian mips has changed to mipseb.
(3) Big endian arm has changed to armeb.

Some additional changes are needed to make 'make universe' work on arm
and mips after this change, so those are commented out for now.

UPDATING information will be forthcoming. Any remaining rough edges
will be hammered out in -current.

Allow building a cross-kgdb for ia64.

Start the dreaded NOFOO -> NO_FOO conversion.

OK'ed by: core

Fix previous commit. GDB_CROSS_DEBUGGER needs to be defined for all
subdirectories.

Makefile (only) changes to allow building a cross debugger.

Prepare for upcoming Binutils house cleaning.

We don't have to reach into binutils/doc anymore for inc-hist.diff
The file was repo copied into our doc directory.

Add bmake glue for gdb 6.1.1. Supports alpha, amd64, i386, ia64
and sparc64.

Note that the debugger doesn't support threading, nor kernel
debugging yet.
