Some of these are guesses, if you know different, just yell.

Now a bfd knows whether underscores are normally prepended
to symbols in its file format. Helps with error messages.
* aout-adobe.c, aout-target.h, bout.c, coff-a29k.c, coff-h8300.c,
coff-z8k.c: targets set so they have leading underscore
* coff-i386.c, coff-i960.c, coff-m68k.c, coff-mips.c, coff-m88k.c,
coff-rs6000.c, coff-we32k.c, elf.c, ieee.c, srec.c: targets set
without leading underscore flag
* targets.c: add symbol leading char to xvec description
* bfd-in.h (bfd_get_symbol_leading_char): new macro.
