Thanks. I wasn't even seeing the failing tests, due to errors from GDB:

Dwarf Error: wrong version in compilation unit header (is 5, should be
2, 3, or 4) [in module
/home/jwakely/build/powerpc64le-unknown-linux-gnu/lib
stdc++-v3/testsuite/cxx11.exe

This meant they were UNSUPPORTED on my test machine.

I've pushed Philipp's [PATCH 1/2] now. Thank you both.
