This includes removing all vestiges of the old not-really supported
ability to build cross tools targeting non-FreeBSD systems, such as
m68k Lynx and NetBSD. Move as much duplicated code from platform
Makefiles into the shared Makefiles. Add a simple mechanism for
specifying ELF 'ldscripts'. Also share as many .h files as possible
(now a single bfd.h vs. one per platform).
Use WARNS?= instead of WARNS=
For this to work properly for all part is the subdirectories
the WARNS assignments in Makefile.inc0 are moved to the correspondning
Makefile.inc.

FreeBSD. This method attempts to centralize all the necessary hacks
or work arounds in one of two places in the tree (src/Makefile.inc1
and src/tools/build). We build a small compatibility library
(libbuild.a) as well as selectively installing necessary include
files. We then include this directory when building host binaries.
This removes all the past release compatibilty hacks from various
places in the tree. We still build on tip of stable and current. I
will work with those that want to support more, although I anticipate
it will just work.
Many thanks to ru@, obrien@ and jhb@ for providing valuable input at
various stage of implementation, as well as for working together to
positively effect a change for the better.
(the two may be different (ie, build vs. runtime))
Allow ldscript's SEARCH_DIR do be rooted somewhere other than `/'.
(in this case at TOOLS_PREFIX)
These changes are most helpful during `make buildworld' so that the shared
libs built in the middle of `make buildworld' are used vs. the ones in
/usr/lib on the build machine.

misuse of /usr/src/include headers. This REALLY fixes
the 20010919 src/UPDATING entry.
With this patch the 4.2-RELEASE box was able to survive
the 5.0-CURRENT "make world".

end of the include searching. We really need a real fix for the issue of
which set of headers to use in compiling the cross-tools -- /usr/include,
or /usr/src/include.
libraries in LDADD so that `make checkdpadd' doesn't report non-errors.
Fixed some style bugs (the usual ones for DPADD and LDADD, and misformatting
of $FreeBSD$).
was already put in SRCS by the general yacc rules. Putting ldemul-list.h
in SRCS fixes races in `make -jN' when .depend hasn't been made.
Don't forget to clean ldemul-list.h.
support building it for variant architectures. It was already
becoming clear that the former structure was too rigid and didn't
scale well.
The usual sort of makefile magic arranges to .include an architecture
specific makefile "Makefile.${MACHINE_ARCH}" in each directory
where it exists. Also, sources will be found in each subdirectory
"${MACHINE_ARCH}" that exists. This is all taken care of automatically
by the top level "Makefile.inc0".
This all seems to work right for the i386 now. I have also converted
those alpha pieces already present to the new schema as best I
could.
Also: change the BINDIR on the i386 to /usr/libexec/elf for "ar"
and "ranlib". They are not object format independent enough to
put into /usr/bin.
