It sounds like you should be using either mips-elf or mips64-elf,
depending on whether you want 32-bit or 64-bit code. From the
options quoted above (particularly -mgp32), I'm assuming you
actually want 32-bit code, so it should be mips-elf.
Note that modern versions of gcc support -march=vr4130. It's
probably worth using that instead of -mips3: it should produce
significantly better code. Indeed, if you configure gcc using
--with-arch=vr4130, -march=vr4130 will actually be the default,
and all the gcc target libraries will take advantage of the
VR4130 extensions.
