Thanks, just a couple of comments.

You have many unnecessary configure flags there.  You should be able
to remove these ones:

armv7: --enable-neon --disable-shared --enable-static --disable-mmx --disable-iwmmxt
armv6: --disable-neon --disable-shared --enable-static --disable-mmx --disable-iwmmxt
i386:  --disable-neon --disable-shared --enable-static --disable-iwmmxt

These are all either the default setting or automatically detected.
I'm not sure what the default for --enable/disable-pic ends up being
with the Apple tools.  Also, why do you disable mmx for the i386 build?

You might also want to mention where to find gas-preprocessor.pl.
