pm_to_blib is really really loud

I’ve been working on quieting down the build system output so that warnings are more obvious. A third of the output is this spew from pm_to_blib:

This is basically an upstream bug; There's no way to suppress that spew.

I've filed a bug asking for an option, but we'd probably have better luck with a patch as well.

If someone wants to try to write a patch, the (current) source is at ​http://cpansearch.perl.org/src/ANDYD/perl5.003_07/lib/ExtUtils/Install.pm. I might try to figure out how options are typically handled in this module, and then it'd just be a matter of sticking an if $we_should after two print statements.
