Quoted from the various GCC-Readme's:

This was at least true for gcc-2.3.1 which we use as
a 68k crosscompiler on our Mips's. I don't know if things
have changed...

That might lead us into trouble. Who has a Mips except me ?

I don't understand why. Gas exists for MIPS, ld should not be a
problem, there are no strange data types ...

me (or rather our institute).
