With a patch moving the dep to a recommends it would be useful if xrdb
was configured with something like:

    --with-cpp=/usr/bin/cpp,/usr/bin/mcpp

so that mcpp could be used as a lightweight alternative. cpp-5
currently carries this giant unstripped library in stretch:

    $ du -h /usr/lib/gcc/x86_64-linux-gnu/5/cc1
    130M    /usr/lib/gcc/x86_64-linux-gnu/5/cc1
