Add GENASSYM_CPPFLAGS in two more places.

Use <bsd.klinks.mk>

Major overhaul:

1) Add support for multiple filesystems including ffsv1, ffsv2, lfsv1 and lfsv2.
(ffsv1 and lfsv2 are known to work. ffv2 support needs more work. lfsv1 is
probably untested.)

2) Only 32-bit Fcodes are used. All 64-bit math uses two cells. This means it
should work on 32-bit machines.

Additional work to consider:

1) Rename genfth.cf to genffs.cf, or keep it and move the ffs symbols to genffs.cf

2) Move the ffs code and the lfs code to different source files so you can
selectively fload the just the filesystems you want.

3) Add code to load ELF files directly instead of relying on the host firmware
ELF support. But, since the binary is now 7250 bytes there may not be room.

branches: 1.12.2;
assym.fth.h also requires sparc symlink. Fix build without DESTDIR.

branches: 1.11.2; 1.11.8;
Use ${TOOL_AWK} instead of ${AWK} or plain "awk" in make commands.
Pass AWK=${TOOL_AWK:Q} to shell scripts that use awk.

branches: 1.10.56; 1.10.60; 1.10.66;
Add src/common/include to include header search path since
<sys/device.h> includes <prop/proplib.h>.

branches: 1.9.4; 1.9.8;
merge ktrace-lwp.

branches: 1.8.2;
Use TOOL_GENASSYM. Part of PR toolchain/30350

Use ${HOST_SH} instead of `sh'.

If necessary, pull in <bsd.sys.mk> to get the definition of HOST_SH;
Makefiles that pull in one of (most of) <bsd.*.mk> will get this anyway.

sprinkle some: libkern.h, some -ffreestanding and some cast-y goodness,
all for the pleasure of the gcc 3 :-)

Rename a large chunk of the make(1) variables which refer to a
program/tool from "FOO" to "TOOL_FOO". The new variables are:
TOOL_ASN1_COMPILE TOOL_CAP_MKDB TOOL_CAT TOOL_CKSUM TOOL_COMPILE_ET
TOOL_CONFIG TOOL_CRUNCHGEN TOOL_CTAGS TOOL_DB TOOL_EQN TOOL_FGEN
TOOL_GENCAT TOOL_GROFF TOOL_HEXDUMP TOOL_INDXBIB TOOL_INSTALLBOOT
TOOL_INSTALL_INFO TOOL_M4 TOOL_MAKEFS TOOL_MAKEINFO TOOL_MAKEWHATIS
TOOL_MDSETIMAGE TOOL_MENUC TOOL_MKCSMAPPER TOOL_MKESDB
TOOL_MKLOCALE TOOL_MKMAGIC TOOL_MKTEMP TOOL_MSGC TOOL_MTREE
TOOL_PAX TOOL_PIC TOOL_PREPMKBOOTIMAGE TOOL_PWD_MKDB TOOL_REFER
TOOL_ROFF_ASCII TOOL_ROFF_DVI TOOL_ROFF_HTML TOOL_ROFF_PS
TOOL_ROFF_RAW TOOL_RPCGEN TOOL_SOELIM TOOL_SUNLABEL TOOL_TBL
TOOL_UUDECODE TOOL_VGRIND TOOL_ZIC

For each, provide default in <bsd.sys.mk> of the form:
TOOL_FOO?= foo
and for the ${USETOOLS}=="yes" case in <bsd.own.mk>, provide override:
TOOL_FOO= ${TOOLDIR}/bin/${_TOOL_PREFIX}foo

Document all of these in bsd.README.

This cleans up a chunk of potential (and actual) namespace collision
within our build infrastructure, as well as improves consistency in
the share/mk documentation and provision of appropriate defaults for
each of these variables.
