A build of the top of GCC 7.0 trunk for the hppa2.0w-hp-hpux11.11 target fails
on x86_64-*-linux in the following self test.

The following options were used to configure GCC:

--enable-languages=c,c++ --enable-checking=all --enable-valgrind-annotations
--prefix=/build/sysroot/hppa2.0w-hp-hpux11.11 --build=x86_64-pc-linux-gnu
--host=x86_64-pc-linux-gnu --target=hppa2.0w-hp-hpux11.11 --without-headers
