These patches bring 1.1.2 inline with egcs-devel.
I'm dissapointed that FreeBSD configuration fixes from -devel aren't
making it into the release branch.

ChangeLog:
* config.guess: Recognize FreeBSD using ELF automatically.

gcc/ ChangeLog:
* configure.in (FreeBSD ELF): Needs extra crt files.
* i386/freebsd*.h Be compatable with stock compiler, which allows '$'
in label names and does not use the the PCC struct return method.
