dev-lang/perl: More TC love for nm/cpp/ranlib re bug #723734

While this won't fix the warnings about hints/linux.sh, as that is
something too complex for me to trivially fix, it should mitigate the
warnings about nm and cpp, and additonally, guards against a possible
future where ranlib is also nuked and later tried to be used from
$Config{ranlib}

-r bump for compile propagation reasons, real delta:
