Subject: Allow CPP override in ENV

When Perl is built with -Dcpp="$(gc-getCPP)", the end result is:

- $Config{cpp} = "${CHOST}-gcc"
- $Config{cpprun} = "${CHOST}-gcc -E"

And of course, Devel-NYTProf uses the former, and so it tries to compile
the damn header instead of just preprocessing it.

This provides a correction, and an override.
