It looks like the whole configure part is broken, assuming that MIPS CPU
are all sicortex (which is a platform dead for years) and that 32-bit
CPU are using the N32 abi.
It happened to build on mipsel because passing -arch=mipsel is not
recognized. Maybe that's the way to go, passing something like
-arch=generic to disable parts of the configure script?
