The riscv64 bridge in that patch is a copy of the mips64 one and
presumably doesn't work yet, and the question is how to get it working?

What might be useful is the notes at
https://wiki.openoffice.org/wiki/Lazy_Hackers_Guide_To_Porting which I
put together long ago, it's all out of date, but from point 11
downwards it might still be of some use to see how to incrementally get
a bridge working where IIRC the old

"cd testtools
build"

should be the new

"cd testtools
make check"

Knowing what libffi does for some of the similar things will help
