06d6e4fcfe This are the build infrastructure changes to allow to use the
Intel C/C++ compiler (lang/icc) to build the kernel.

The icc CPUTYPE CFLAGS use icc v7 syntax, icc v8 moans about them, but
doesn't abort. They also produce CPU specific code (new instructions
of the CPU, not only CPU specific scheduling), so if you get coredumps
with signal 4 (SIGILL, illegal instruction) you've used the wrong
CPUTYPE.

Incarnations of this patch survive gcc compiles and my make universe.
I use it on my desktop.

To use it update share/mk, add
	/usr/local/intel/compiler70/ia32/bin	(icc v7, works)
or
	/usr/local/intel_cc_80/bin		(icc v8, doesn't work)
to your PATH, make sure you have a new kernel compile directory
(e.g. MYKERNEL_icc) and run
	CFLAGS="-O2 -ip" CC=icc make depend
	CFLAGS="-O2 -ip" CC=icc make
in it.

Don't compile with -ipo, the build infrastructure uses ld directly to
link the kernel and the modules, but -ipo needs the link step to be
performed with Intel's linker.

Problems with icc v8:
 - panic: npx0 cannot be emulated on an SMP system
 - UP: first start of /bin/sh results in a FP exception

65d2bdc62c Fixed bogus ${FOO:Mbar} tests where the actual intent is to check
if the result set is empty.  While here, replaced non-bogus empty
string comparisons with equivalent empty() checks.

6b14fdfa52 Guess better the source for object files in case .depend file is
missing and there are multiple choices using multiple inference
(suffix transformation) rules.

This is known to fix compilation of s_log1p.o in lib/msun on i386,
as otherwise it attempted to use s_log1p.S as the source (which is
marked broken) instead of legal s_log1p.c which is in CFLAGS.  The
normal case where .depend file exists is not affected.

11dc929821 Introduce DPSRCS, that holds the list of source files which are
needed for generating dependencies.  SRCS are always part of it,
and normally only they.

This can be useful in some random cases where it's necessary to
have something in .depend that isn't part of SRCS.  This will be
used to replace a hack in lib/libpam/libpam/Makefile.

484933a925 - Replaced several := ops with their += equivalents; the old
form became unnecessary with the bsd.prog.mk,v 1.69 change.

- Eliminated duplicate y.tab.h in SRCS.

Reviewed by:	bde

- Complementary to the said bsd.prog.mk change, use the fact
  that inner .for loops are not real loops but a tricky form
  of a local macro for the outer loop's variable, and switch
  to using faster variable modifiers to replace extensions.

2e3c617921 Use make(1) instead of a shell script to implement the checkdpadd target.
This is simpler, and is easy to do now that make(1) supports substituting
regexps.  Fixed missing '$' anchor in the regexp.  Use less cryptic names
for temporary variables.

a51613b6da There's no reason to keep separate AINC knob anymore.
The only real use of it (lib/libc/Makefile) has been

ccc4bab104 Added the new variable CTAGS which, if set to "ctags", reverts

Made GTAGSFLAGS and HTAGSFLAGS overrideable, added CTAGSFLAGS.
Folded bsd.prog.mk version of `tags' into bsd.dep.mk.

66422f5b7a Initiate deorbit burn for the i386-only a.out related support. Moves are
under way to move the remnants of the a.out toolchain to ports.  As the
comment in src/Makefile said, this stuff is deprecated and one should not
expect this to remain beyond 4.0-REL.  It has already lasted WAY beyond
that.

Notable exceptions:
gcc - I have not touched the a.out generation stuff there.
ldd/ldconfig - still have some code to interface with a.out rtld.
old as/ld/etc - I have not removed these yet, pending their move to ports.
some includes - necessary for ldd/ldconfig for now.

Tested on: i386 (extensively), alpha

b25a566d47 Merge bsd.obj.mk's version of the _SUBDIR target with bsd.subdir.mk.
Ensure all standard targets honor SUBDIR.  Now `make obj' descends into
SUBDIRs even if NOOBJ is set (some descendants may still need an object
directory, but we do not have such precedents).  Now `make install' in
non-bsd.subdir.mk makefiles runs `afterinstall' target _after_ `install'
in SUBDIRs, like we do in bsd.subdir.mk.  Nothing depended on the wrong
order anyway.

Fixed `distribute' targets (except for the bsd.subdir.mk version) so that
they do not depend on _SUBDIR; `distribute' calls `install' which already
depends on _SUBDIR.

De-standardize `maninstall', otherwise manpages would be installed twice.
(To be revised later.)

afabc4dfc2 Removed bogus env(1) commands. make(1) uses a real shell, so
"env name=value ... cmd ..." was just a pessimized way of doing
"name=value ... cmd ...".  Note that make(1) can't optimize
either of these to an exec of env(1) or "cmd" even if the second
"..." is simple, since it can't tell that the shell metacharacter
in "name=value" is actually handled by env(1).

70a6e3314e Support Objective C almost as well as C++.
Notes:
- We no longer use -fgnu-runtime in bsd.lib.mk, since it is the default
  and bsd.lib.mk is the wrong place to override it.
- Gnu C doesn't have a special compiler driver for Objective C like it
  does for C++.  The defaults are suitable for Gnu C.  Use `OBJCLIBS='
  in /etc/make.conf for POC.

e1eecc081e Add `B' to list of flags to pass through from C*FLAGS when using mkdep
(bsd.dep.mk) and compiling assembly language sources (bsd.lib.mk).
This doesn't change anything for our current source tree, but if you
want to use the -B switch in C*FLAGS to specify the location of
compiler subprograms, now you can do it.

663e9677d5 Use ld -f' (actually cc -Wl,-f') at `make depend' time to generate
almost perfect dependencies on crt0's and libraries.  DPADD and
bsd.libnames.mk should go away soon.  Use a new _EXTRADEPEND target
to implement this and to avoid editing of .depend when .depend isn;t
being rebuilt.  The afterdepend target doesn't seem to be good for
anything and is now unused.

Fixed LDDESTDIR for the DESTDIR case when ${SHLIBDIR} != /usr/lib.

Added commented-out -nostdlib to LDDESTDIR for the DESTDIR case.
The wrong libraries may be used without this; however it breaks
linkage to crt0 and libc.
