PR23691, gas .y files vs. automatic make dependencies
A number of targets, bfin, rl78, rx, can show odd failures when
bfd/reloc.c changes BFD_RELOC_* enum values, if recompiling over a
build dir with existing objects. The problem is caused by
bfin-parse.o and similar not being recompiled and so using stale
BFD_RELOC_* values. This isn't fixed by making bfin-parse.c depend on
bfd/reloc.c, which isn't necessary anyway. bfin-parse.o should have
been recompiled due to bfd/bfd.h changing when extracted bfd/reloc.c
BFD_RELOC_* values change, but that wasn't happening. The problem is
that automake generates a makefile that loads gas/config/.deps/
dependency file for objects with corresponding sources mentioned in
EXTRA_as_new_SOURCES. Unless we want to mess around generating
explicit dependencies, I think that mean moving some object files to
the build gas/config/. This patch does that, removing some hacks for
m68k-parse.c that should no longer be necessary, and removes some
rules that catered to old bison producing code that triggers compiler
warnings.
