A few problems still...

1) The Makefile still puts the ldscripts into /usr/lib/ldscripts, so the mv on x86_64 tries to move them 
from /usr/lib64/ldscripts and fails.

2) I must have been smoking something, glibc-devel.i386 isn't a valid dependency, so the build fails 
even with the i386 glibc-devel package installed on my x86_64 box.

I've been hacking up the Makefile a bit, and I have it tweaked to only build the 64-bit parts, but there's 
an issue there too -- it looks like the 64-bit build depends on some 32-bit stuff, because the build 
fails if I don't also do the 32-bit parts, like so:

+ make -j3

If we can get that resolved, massaging the Makefile really isn't too hard. My current alterations would 
need a fair amount more work to get things playing nice on all arches, but I suppose another potential 
interim solution would be a Makefile patch only applied on 64-bit platforms...
