[Patch] Mach-O: add write capability

- Subject: [Patch] Mach-O: add write capability
Hi,
the Mach-O bfd back-end was mostly a read-only back-end - which is
still very useful but somewhat incomplete.
This patch starts to add write capability. Far from being complete
but I was at least able to objcopy
from binary to Mach-O or from Mach-O object file to Mach-O object file.
Also until now there was only 2 generic targets. I added an i386
targets, others (x86-64, ppc and ppc64)
will come later.
I have also replaced some hard-coded values with constants.
I plan also to port gas to Mach-O as this will be useful to run the
testsuite.
I did some manual checks to test this new feature.
Tristan.
