Subject: Propagate CC to subdirectories

Bug-Debian: https://bugs.debian.org/886160

    pptpd fails to cross build from source, because it fails to propagate CC
    to plugins/Makefile. It is correctly detected by configure and correctly
    forwarded to Makefile.am, but fails being forwarded to plugins/Makefile.

    After making that forwarding explicit, pptpd cross builds successfully.

    Fixes Debian #886160.
