tested all the 8 configurations (mips, mipsel, mipshf, mipselhf, mips64, mips64hf, mips64el, mips64elhf).
tested in QEMU only.

test include build and run, also compiling simple application with gcc in running system.
GCC requires to pass -mhard-float for mips*hf platforms (as it cant find softfloat symbols).
