Make Perl link all .so it builds with libperl.so.

It makes upgrading from one Perl major version to another way easier.  For
binary package users, it means pkg upgrade will detect the libperl.so.x.yy
change, and reinstall the affected packages.  For users using ports, it will
save rebuild time as it's easier to detect what ports really need to be
rebuilt.

+  Perl now links libperl.so with all .so it builds.  The stage-qa checks have
+  been extended to check that libperl.so is in fact linked with .so in
+  SITE_ARCH and errors out if none of the .so build by a port are linked with
+  it.  It also checks that the rpath and runpath elf attributes are present.
