on the setting of ${SHLIBDIR} and ${SHLIBINSTALLDIR} (_not_ ${_LIBSODIR}).
Fixes cruel and unusual ^W^W^W obscure native-build and not-so-obscure
cross-builds problems I was having with shared libraries with a
non-base LIBDIR (e.g, /usr/X11R6/lib) that use LDADD to pull in other
libraries from /usr/lib (such as libm) which are really in /lib and the
symlink from ${DESTDIR}/usr/lib/libm.so to /lib/libm.so.N.M was confusing
the linker. Stuffing -rpath-link ${DESTDIR}/lib in solves the problem.
This should mean that shared libraries that depend upon other shared
libraries in other directories should DTRT in a DESTDIR (cross-)build...
Inspired by _PROGLDOPTS in <bsd.prog.mk>
if we need to add stuff (usually "/lib") to the rpath-link path before
"/usr/lib". Otherwise, this barfs if LIBDIR != /usr/lib or /lib, and
we're cross-building (e.g., in src/x11)
the order that Makefile.inc is pulled in to get this to work.
this stuff needs a rototill (for another day). for example, having every
sys/lkm/** directory make their own machine ${MACHINE_CPU} and possibly
${SHARED_MACHINE_CPU} (e.g, x86 for i386/x86_64) is not the most optimal
situation ...
HAVE_GCC3. if this is set, we also set USE_TOOLS_TOOLCHAIN=no. change
the definition of the former to be restricted to whether tools/toolchain
is used or not.
SYMLINKS to install symlinked header files. INCSYMLINKS are installed with
'make includes'. This avoids using SYMLINKS and hacks with the 'linkinstall'
target in <bsd.links.mk>, as linksinstall occurs in 'make install' and hacks
to get it to occur in 'make includes' weren't robust, as seen in lib/libdes.
Yet more improvements to bsd.README.
* DPSRCS contains extra dependencies, but is _NOT_ added to CLEANFILES.
This is a change of behaviour. If a Makefile wants the clean semantics
it must specifically append to CLEANFILES.
Resolves PR toolchain/5204.
* To recap: .d (depend) files are generated for all files in SRCS and DPSRCS
that have a suffix of: .c .m .s .S .C .cc .cpp .cxx
* If YHEADER is set, automatically add the .y->.h to DPSRCS & CLEANFILES
* Ensure that ${OBJS} ${POBJS} ${LOBJS} ${SOBJS} *.d depend upon ${DPSRCS}
* Deprecate the (short lived) DEPENDSRCS
Update the various Makefiles to these new semantics; generally either
adding to CLEANFILES (because DPSRCS doesn't do that anymore), or replacing
specific .o dependencies with DPSRCS entries.
Tested with "make -j 8 distribution" and "make distribution".
Update documentation for some other make variables

"make: out of memory" problem when make dependencies in lib/libc.
XXX: this is a temporary workaround. i'm working on cleaning up how
the DPSRCS stuff is used throughout the tree...
some build problems where DPSRCS contains .h files that need to exist to
build the .d file.
document that bsd.dep.mk should be included after anything that might
update SRCS or DPSRCS so that the above works correctly, and actually
ensure this is the case.
