Added static subpackage

Hi Erik,
I used mingw-glib2 and mingw-fontconfig as templates to add the static
subpackage.

Keep in mind I'm *not* using Fedora (I rather ported some of its MinGW packages
to Arch linux) so the patch is not tested. Anyway I can confirm the static
library does not need any special treatment to be built.
