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.
- the two `_EXTRADEPEND::' targets potentially clobbered each other for
`make -jN'. In practice, the output for the second target sometimes
disappeared.
- bogus dependencies were generated for static libraries.
headers in ${SRCS}, as in bsd.lmod.mk and bsd.prog.mk. This helps
`make [-j]' work when .depend doesn't exist. Even plain `make'
sometimes only worked because of magic ordering in ${SRCS}.
(as in bsd.prog.mk). Include it if `checkdpadd' is being made, so that
it can be checked until it goes away.
Don't clean files that we don't create.
Fixed style of empty test.
.if in Makefiles. bsd.prog.mk and bsd.lib.mk do not depend on it however.
Allow overriding of the -soname arg when building the lib*crypt.so* libs
since libdescrypt.so and libscrupt.so both need a -soname of libcrypt.so
so that the symlink is obeyed at runtime rather than at compile time.
since 2.1.x make(1) apparently does not have the -m switch to set both
the the bsd.*.mk and sys.mk location, and this breaks 'make world' from a
2.1.x system.
note, using "-Wl,-f" to generate a library objects list doesn't work
anymore since the hack to ld hasn't been incorporated into binutils-2.8.
(and the -f switch is used for something else already)
This is disabled by default, don't panic! :-)
a couple *.mk files to enable -current world building on really old
machines (e.g., 2.1.5).
Reviewed by: too many many people to list here, special thanks to bde
(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.

libraries. Remove the now-unneeded CPLUSPLUSLIB hack. I will also
remove the CPLUSPLUSLIB definitions from the Makefiles that use it,
after the dust settles.
Use gcc's LIBRARY_PATH environment variable to handle DESTDIR,
instead of -L flags in LDDESTDIR. LIBRARY_PATH is documented in
the gcc info pages. It is better than using -L flags, because it
modifies the search for start-up files as well as for libraries.
A new variable LDDESTDIRENV is used to contain the normally-empty
LIBRARY_PATH environment setting.
LDDESTDIR is no longer set in <bsd.lib.mk>. It is still honored for
the time being, because a couple of userland Makefiles still (wrongly)
set it. These should be fixed, and LDDESTDIR should vanish.
Removed the commented-out "LDDESTDIR+=-nostdlib", because "gcc -shared"
doesn't link in any standard libraries anyway.
Removed the ".if defined(LDADD)" around the _EXTRADEPEND target for
shared libraries. This target is always necessary now, because
c++rt0.o is linked into every shared library.
Don't merge this into -2.2 without first merging the support for
"gcc -shared".
Fixed back to front -X and -x strip flags in .m.o and .m.po rules.
Fixed disordered .m.o and .m.po rules. What is .m?
Stripping probably should be removed. It makes problems in library
functions hard to debug...
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.
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
the gnu libobjc rather than the NeXT one. I do not understand objc
so I don't know the implications of this, but the gcc-2.7.2 libobjc is
built with this.
bsd.obj.mk. Also, a make target called objwarn checks to see
if ${.OBJDIR} != ${.CURDIR} and ${.OBJDIR} != ${CANONICALOBJDIR}
and outputs a warning. (No warning for the latter if MAKEOBJDIR or MAKEOBJDIRP
REFIX is set). objwarn is called from all targets in bsd.prog.mk, bsd.kmod.mk,
and bsd.lib.mk.

eliminates many local symbols that could not be removed by the "ld -r -x"
steps on the individual object files. It makes shared libraries
substantially smaller -- almost 11%, in the case of libc.so.3.0.
