("[Driver] Detect libstdc++ include
paths for native gcc (-m32 and -m64) on Debian i386") for the Debian Hurd
case, which has the same multiarch name reduction from i686 to i386.
i386-linux-gnu is actually Linux-only, so this moves the code of that commit
to Linux.cpp, and adds the same to Hurd.cpp
