BFD Mach-O back-end

[Aurelien Chanudet]

Hi all,

There currently exists a partial BFD Mach-O back-end.  This back-end 
was written by Apple engineers and got contributed back to the FSF 
about one year ago, judging from the log in the CVS repository.  BFD is 
used on Mac OS X by gdb only, as far as I can tell.  As gdb doesn't use 
all the parts of BFD that ld, for instance, uses, the existing back-end 
is somewhat incomplete.  Most notably, there is no support for 
relocation.

I extended the back-end to support relocation, and I'm now considering 
implementing linking support.  I'd be pleased to contribute this code 
back to the FSF, which is why I'm posting here.
