official gnu configure scripts and a couple of other places.
Add an example noisy, loud and annoying placeholder for /usr/bin/objformat
if it turns out to too much trouble to be gone. It is not connected to
the build yet.
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
build 2.2-stable worlds on 3.0-current systems again. objformat
calls getobjformat(), which doesn't exist in 2.2's libc.
Technically there should have been a version number bump when it was
added in -current. But it's used in so few places that it hardly
seems worth that. Besides, the objformat program is very heavily
used during a make world; it won't hurt to have it load a little
faster.
Move a.out libraries to /usr/lib/aout to make space for ELF libs.
Make rtld usr /usr/lib/aout as default library path.
Make ldconfig reject /usr/lib as an a.out library path.
Fix various Makefiles for LIBDIR!=/usr/lib breakage.
This will after a make world & reboot give a system that no
longer uses /usr/lib/*, infact one could remove all the old
libraries there, they are not used anymore.
We are getting close to an ELF make world, but I'll let this
all settle for a week or two...
