IRIX may have features that Linux lacks but this is not an example of one. Linux supports 32-bit binaries with 32-bit pointers that run on 64-bit kernels on the other 64-bit archs, like powerpc or sparc64.

This problem is really a quirk that results from the fact that AMD made significant changes to the arch(added 16 registers) when they invented amd64.
