Add explicit configure-time checks for perl.h and libperl.so.
Although most platforms seem to package Perl in such a way that these files are present even in basic Perl installations, Debian does not. Hence, make an effort to fail during configure rather than build if --with-perl was given and these files are lacking. Per gripe from Josh Berkus.
