It might not be documented, but the EABI64 code in gcc supports both
LP32 and LP64, with "-mabi=eabi -mlong32" selecting the 32-bit version.
It's one of the many multilibs built by mips64vrel-elf.

Unfortunately, we even have the -mgp32 -mlong64 version.  In other
words, the EABI code effectively supports the combination {-mgp32,-mgp64}
x {-mlong32,-mlong64}.

But...

...fair enough.  Just thought I'd ask. ;)
