MIPS: Github Actions for validating MIPS
d56fc2e 
It includes running tests in QEMU.

Note: musl based prebuilt toolchains used. Didn't find GLIBC ones.

MIPS DSP: disable DSP code for MIPS64 with DSP
4d2db27 
Because support for MIPS64 DSP in GCC completely broken:
- no builtin functions for mult, madd, msub, extr, shilo
  used here.
- inline assembly with accumulators not works well when
  GCC reaches limit of 4 accumulators: observed in
  xcorr_kernel_mips and silk_warped_autocorrelation_FIX_c.
