Do it for all packages that
* mention perl, or
* have a directory name starting with p5-*, or
* depend on a package starting with p5-
like last time, for 5.18, where this didn't lead to complaints.
Let me know if you have any this time.
a) refer 'perl' in their Makefile, or
b) have a directory name of p5-*, or

ExtUtils::CppGuess attempts to guess the system's C++ compiler that
is compatible with the C compiler that your perl was built with.
It can generate the necessary options to the Module::Build constructor
or to ExtUtils::MakeMaker's WriteMakefile function.
