I'm not, but it doesn't make sense if you don't configure gcc in certain
non-default way, you get dozens of FAILs during the make check.
If libvtv doesn't work at all without --enable-vtable-verify, perhaps it
shouldn't be built, or at least make check shouldn't be run?
Does --enable-vtable-verify affect anything but the 4 extra objects built in
libgcc subdir that aren't actually linked into libgcc / libgcc_s?
