-march=m6201 is not yet supported in GCC upstream, so disabling all versions when selecting this core. Note that M6201 implies a MIPS R6 CPU, and some GCC versions are already disabled for R6, so we don't need to disable those ones for M6201 as well. The external Codescape IMG GNU Linux Toolchain has support for this core.
