07b202a847 Define several extra macros in bsd.sys.mk and sys/conf/kern.pre.mk, to 
get rid of testing explicitly for clang (using ${CC:T:Mclang}) in
individual Makefiles.

Instead, use the following extra macros, for use with clang:
- NO_WERROR.clang       (disables -Werror)
- NO_WCAST_ALIGN.clang  (disables -Wcast-align)
- NO_WFORMAT.clang	(disables -Wformat and friends)
- CLANG_NO_IAS		(disables integrated assembler)
- CLANG_OPT_SMALL	(adds flags for extra small size optimizations)

As a side effect, this enables setting CC/CXX/CPP in src.conf instead of
make.conf!  For clang, use the following:

CC=clang
CXX=clang++
CPP=clang-cpp

4f88092408 Consolidate duplicate definitions of V86_CY() and V86_ZR() which check for 
the carry and zero flags being set, respectively, in <btxv86.h> and use
them throughout the x86 boot code.

2754fe609d Upgrade our copy of llvm/clang to r126079, from upstream's trunk. 
This contains many improvements, primarily better C++ support, an
integrated assembler for x86 and support for -pg.

d05becf2b6 Use -Wl,-N instead of the undocumented -N option for GCC. 
GCC forwards the -N flag directly to ld. This flag is not documented and
not supported by (for example) Clang. Just use -Wl,-N.

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

2a53f3fb35 Major cleanup of bsd.lib.mk. 
Get rid of the INTERNALSTATICLIB knob and just use plain INTERNALLIB.
INTERNALLIB now means to build static library only and don't install
anything.  Added a NOINSTALLLIB knob for libpam/modules.  To not
build any library at all, just do not set LIB.

95cfc25d0d Back out last commit. I expect our bsd.*.mk gods to remove the need for 
defining so many extra things in addition to INTERNALLIB.  We don't like
repetitive C code and we shouldn't for make code either.

3bf8b9cee3 NOPIC, NOPROFILE, NOMAN, and INTERNALSTATICLIB are redundant when using 
INTERNALLIB now.
