I once tried to build GMP for a toolchain that defaults to coldfire
-- picked a 5475 randomly -- and had to fallback to the C impl in gmp
(http://repo.or.cz/w/buildroot.git?a=blob_plain;f=package/gmp/m68k-coldfire-for-libgmp.02.patch;hb=HEAD
attached)
Perhaps you could give gmp-4.3.1 a try if you have a minute and
eventually take care of pushing a fix upstream?
TIA,
