MIPS: add support for M5101 cores

Browse Source 
-march=m5101 support starts from GCC-6, so disable previous versions
when selecting this core.

Note that M5101 implies a MIPS R5 CPU, and some GCC versions are already
disabled for R5, so we don't need to disable those ones for M5101 as
well.

Also disable external toolchains that don't support this core.
