MIPS: mm: Only build one microassembler that is suitable 2014-11-24T06:45:36+00:00 Maciej W.

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.
