Update MIPS kernel builds to work with mips-gcc.

- Use a default -march of mips64 on N64 and N32 kernels.
- Set the endianness (via MIPS_ENDIAN) and ABI (via MIPS_ABI) in
  CFLAGS from MACHINE_ARCH.  ARCH_FLAGS now only sets a different
  -march value if needed.
- TRAMP_ARCH_FLAGS inherits MIPS_ENDIAN from MACHINE_ARCH but does
  not set the ABI since XLPN32 needs an N64 ABI for the trampoline
  loader.  When TRAMP_ARCH_FLAGS is used it must set both -march
  and -mabi.
