Commit1b974425(MIPS: add support for M6201 cores) explained that the new core was not supported by upstream gcc, and as of gcc-8-trunk that's still the case. Ditto for3cfbeb83(MIPS: add support for P6600 cores). This means that we currently allow to build an internal tolchain for those cores, yet we have no suitable gcc version. Disable the internal backend in this case. Signed-off-by: "Yann E.

libmudflap is a gcc library used for the mudflap pointer

use the -fmudflap gcc flag.

See http://gcc.gnu.org/wiki/Mudflap_Pointer_Debugging and

the help of the gcc -fmudflap option for more details.
