Yes.

Currently, this would require a complete reinstall.  In any case, n32
userland is really not ready for general consumption yet.  There are
known bugs that we haven't squashed, and that could cause serious pain
to end users.

Of course it can't.  It has no 64-bit library to link the binary
against.  However, you should still be able to build 64-bit object
files, and other programs that don't need a libc (like the kernel).

If you do install n32 userland, your toolchain will be
mips64-unknown-linux-gnu, and will produce n32 userland binaries just
fine via -mabi=n32.  However, then -mabi=32 and -mabi=64 won't work,
since there are no o32 or n64 libs to link against.  Makes sense, yes?
