If you force short addressing to a globl symbol, you do something wrong.
jbsr triggers automatic relaxing, bsrs does not.  Using the latter would
be a user error.  For jbsr the assembler should do the right thing.

Embedded elf targets are exempted from the rule that references to globl
symbol cannot be relaxed, on the grounds that they don't have shared
libraries (see relaxable_symbol in tc-m68k.c).  Seems like
TC_RELOC_RTSYM_LOC_FIXUP needs some fixup.
