Looking at the source, it is just a copy of rpmvercmp from rpm.
Fooling around with pkg-config, it seems that 1.0rcX is considered
less than 1.0.0, but 1.0.0rcX is considered greater than 1.0.0. So, if
your release numbering is as you show above, I think it would work for
`pkg-config --exists mypackage >= 1.0rc0'.
