I fear you may have copied the wrong one here, the MIPS implementation seems
more complex than the rv64 or arm64 versions, and you should not need that
complexity.
Can you try removing the genvdso.c file completely? To be honest I don't
see why this is needed here, so I may be missing something, but the other
ones don't have it either.
