[oe] [PATCH 01/44] cpan-base: add perl version to PR

[Roman I Khimov]

Makes perl modules rebuild on perl version change, since binary compatibility
could be broken with that (although perl itself tries to maintain it  within
patchlevel range, like 5.8.7 -> 5.8.8).

This is conditional on PACKAGE_ARCH, since there is nothing to rebuild for
pure perl modules (and those should use 'PACKAGE_ARCH = "all"') even if they
break with perl version change.

This also should ease transition to perl 5.10.1.
