file so that we have a chance of using gcore on non-i386 platforms. Use
linker sets to reduce the registration glue. Remove md-sparc.c, we do not
have an a.out sparc32 port. aoutcore.c was repocopied from gcore.c.
All Makefiles now use MACHINE_ARCH for the target architecture.
Unification is required for cross-building.

fixed typo: MACHINDE -> MACHINE_ARCH
automagically. -lfoo has to be right to work, but ${LIBFO0} is too
easy to forget or misspell; nothing checks it and it should be
different for shared libraries.
