The microMIPS patch added microMIPS multilibs to mips*-sde-elf.  The 32-bit
ones build fine, but the 64-bit ones don't, at least not with FSF binutils.
My impression from:

    http://www.cygwin.com/ml/binutils/2010-07/msg00405.html

was that this is expected -- 32-bit has been extensively tested, but the
64-bit side was more theoretical at this stage.

This patch therefore disables the 64-bit microMIPS multilibs,
as is already done for MIPS16.  Tested on mips*-sde-elf and applied.
We should consider reverting it once 64-bit microMIPS is known to work
and be useful for at least one core.

Thanks,
Richard
