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.
Bug: https://github.com/timbunce/devel-nytprof/issues/139
