fix $VERSION assignment
use an architecture-sensitive filename
changelog for VERSION fix

version.pm bundled with EUMM "v0.88" but not the same as cpan v0.88, and
errors with "defines neither package nor VERSION--version check failed" when a
module exists in %INC but has no $VERSION defined.

Another workaround would be to reinstall version.pm from the CPAN (any version
from 0.88 and up seems to do) to overshadow EUMM's bundled version.

perls up to 5.13.8 are affected, because those versions shipped
version.pm at a version less than 0.88.

          - work around issues with EUMM-bundled version.pm by properly
            fudging a VERSION during testing (affected perls before 5.13.9)
