bsd.lib.mk and thus broke the build since AFLAGS were not taken
into considered anymore, as bsd.lib.mk currently has wrong .s.o
rule that uses cc(1) instead of as(1).
Revision 1.14 reverted to using as(1), and revision 1.15 brought
AFLAGS back to the business, but revision 1.14 also broke "make
clean".
To fix this, but not break anything that was fixed in revisions
1.13-1.15, we revert mostly to revision 1.13 except for switching
back to using bsd.prog.mk. This gives us back the default .s.o
rule from sys.mk that uses as(1), and fixes "make clean" by
restoring the full contents of OBJS.
Also fixed LDFLAGS.
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
