The current Mips CPU config.mk code always expects a Mips 4kc core and toolchain. This is not appropiate for other toolchains and CPUs/SoCs.
Replace the current MIPSFLAGS code by cc-option macro and use -march=mips32r2 as default optimization level for all Mips32 CPUs. Replace the endianess determination code from toolchain prefix by a more generic one inspired by the Linux arch/mips/Makefile.
