Since truss also uses kdump's mkioctls script, pass the value of ${CPP}
there too, similar to r234058.

MFC after: 1 week

It turns out that truss also used kdump's mkioctls script, and expected
ioctlname() to return a pointer to the name rather than print it. This did
not show up in testing because truss had its own prototype for ioctlname(),
so it would build fine and run fine as long as the program being traced did
not issue an ioctl.

Teach mkioctls to generate different versions of ioctlname() based on its
first command-line argument.

Fix breakage introduced in r211725 and improve functionality of truss on
64-bit powerpc by adding 32-bit compatibility features.

MFtbemd:

Prefer MACHNE_CPUARCH to MACHINE_ARCH in most contexts where you want
to test of all the CPUs of a given family conform.

Build usr.bin/ with WARNS=6 by default.

Also add some missing $FreeBSD$ to keep svn happy.

Teach truss about 32-bit FreeBSD and Linux binaries on amd64. Some
additional work is needed to handle ABI-specific syscall argument parsing,
but this gets the basic tracing working.

Revert CLEANDEPFILES commit per ru@'s request; it does not really solve
the problem. The correct fix will follow.

Normally, when a header file is removed from the build (as i4b headers
were recently), a simple 'make cleandepend; make depend' is sufficient
to keep the tree buildable after a cvs update when doing incremental
builds.

However, kdump and truss use a script which searches for header files
that define ioctls, and generates C code that includes them. This
script will usually not need updating when a header file is removed,
so the normal dependency mechanism will not realize that it needs to
be re-run. One is therefore left with code that references dead files
but will only be removed by a full 'make clean', which defeats the
purpose of incremental builds.

To work around this, modify the cleandepend target in bsd.dep.mk to
also remove any files listed in a new variable named CLEANDEPFILES,
and modify kdump's and truss's Makefiles accordingly.

decode fcntl and mmap arguments.

Use cat(1) instead of cp(1) so as not to break -DNOCLEAN builds
when the file permissions of source files don't allow writing.

Removed extra parentheses.

Ported to sparc64.

I now don't seem to be able to reproduce the -DNOCLEAN buildworld
breakage with ioctl.c. The .depend file should track dependencies
just fine, and the worst we can have is to miss new ioctls.

But I still think it's a good idea to have -DNOCLEAN build produce
the same ioctl.c as it would without -DNOCLEAN.

Alpha support for truss. I tested this on both bento and beast (thanks,
Jordan, for pointing me at beast!). There should be no change for the
i386 version.

Revert the changes yet again, after some email from Bruce. Sorry.

Proper way to do the previous mis-commit. Still not quite right, because
some header files (e.g., <err.h>) include <machine/something.h>, and this
will not pick up the right header files, so it may be removed eventually
anyway. But some people who are not willing to build the right way
apparantly want this, so this is for them.

Get rid of the bogus include -- it is incomplete (as it doesn't handle
anything other than <sys/*.h>), and unnecessary in most cases. (The
situations where it is necesary can be dealt with by manually-made symlinks,
which is acceptable since they should only occur during testing. Remember:
the tree does not compile well if you do not have matching header files
installed. Half-baked -I directives don't cover enough of the cases.)

include sys so it builds on 2.2.x
also, fix misspelling of -1 (as EOF for getopt)

First cut at printing out ioctl names intelligently. Note that this doesn't
handle linux ioctls (yet?). This uses the mkioctl script from kdump,
bless its little heart.
