This is probably a stupid question, but couldn't you just cross-compile from a Linux box?

It is, shall we say, "non-trivial" to build a GCC cross-compiler for IRIX.  I've done it in the past.  I may be foolish enough to attempt it in the future.  It's a lot of work to get the full build environment set up and working.  And even more work to actually use that cross-compiler to build working software.

And, FWIW, when I did build cross-compilers for IRIX, I still disabled multilib and built them to target N32 only.

IME, building the cross-compiler would be as much work as (maybe more than) what Raion is doing.
