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.
