MIPS: mm: Only build one microassembler that is suitable
The microMIPS microassembler is only suitable for configurations where the kernel itself is built to microMIPS machine code and not where only user microMIPS software is supported. The former is controlled with the CPU_MICROMIPS configuration setting, whereas SYS_SUPPORTS_MICROMIPS is used for the latter. Not only that, but with a given microMIPS vs standard MIPS kernel configuration only one microassembler is needed, that matches the ISA selected -- CP0.Config3.ISAOnExc is mandatory on microMIPS processors, so there is never a need to mix microMIPS and standard MIPS code. Consequently build only the microassembler that matches the ISA selected for the kernel. Signed-off-by: Maciej W.
