This is basically what I did too.

Yes, but it doesn't need to - the asm spec is passing -arch <arch>
unconditionally, but only Apple's assembly can deal with it.  That
bit of spec needs to go to config/darwin.h.

Still, that only gets you to where the dwarf2 output stuff chokes.

I'm dealing with the consequences of a messy import of FSF sources
right now, but when that's done (day or two, tops), I'll be finishing
up the Linux build issues.
