  Yes, it's rare. However, according to config.sub from GCC [1], it's not

Good! We woudn't want to be gaoled for a CPU moniker!

  I ran it on a LFS rootfs provided by Loongson (A Chinese MIPS64r2


It seems that GMP's configfsf.sub also has that.  Now, I have no idea
what it means.  Is is just a novel name for mips64r2el or is it somehow
a different ABI?

If you make the obvious change to, then build twice, once
with --disable-shared and once with --disable-static, does

  make && make check

run to without any errors.  (OK, you told me you were cross compiling,
so perhaps that will require some intermediary command.  And "make check
TESTS=" for just building the tests would perhaps be useful.)
