Commit d148c963 authored by Tom Finegan's avatar Tom Finegan

Add mips32 support to the cmake build.

Requires use of new cmake toolchain file:
$ cmake path/to/aom -DCMAKE_TOOLCHAIN_FILE=path/to/aom/build/cmake/toolchains/mips32-linux-gcc.cmake

DSPR2 and MSA are supported via addition of -DENABLE_DSPR2=1 and
-DENABLE_MSA=1 respectively. Note that the latter requires the addition
of -DMIPS_CPU=p5600.
