 has landed in gcc trunk as well as on gcc-6-branch and gcc-6-branch. If
 MacPorts adopts this patch for their gcc packages, the --with-local-prefix
 usage can be dropped from the Portfiles and the sandbox blacklisting of
 /usr/local be relied upon instead of the package builds of those compilers
 and their usage within other MacPort package builds.
