add support for GCC 6.4.0 GCC 6.4.0 has one big advantage over 6.3.0: it is shipped as .tar.xz, shaving 30 MB from its download size, and also considerably speeding up the extraction process. All patches are copies of the GCC 6.3.0 ones, except 0004-posix_memalign.diff which was rebased to apply cleanly. 0014-ubsan-empty-string-fix.diff was removed, since it was upstreamed.
