Well, I can confirm that it gets the build past the point of failure that I
originally mentioned... now I'm seeing a different failure in
libstdc++-v3/src/filesystem/dir.cc though, but I think it's unrelated to this
one; I think I had to pass the '--disable-libstdcxx-filesystem-ts' flag to
configure last time to get past it... I'll open a new PR about it. (Your patch
should be good enough to close this one, though.)
