* subsegs.c (subseg_change): allow and handle a change into SEG_BSS.
* tc-m68k.c (m68kip): Fix typo so that only arch's >=68020 do
pcrel data stuff. (md_estimate_size_before_relax): when relaxing a
68010 bxx into a bra+6 jmpxx, put the bytes of the jmp opcode into
the right place. (s_bss): Don't put .bss stuff into SEG_DATA, put
it into SEG_BSS
