mingw32-liboil

[Farkas Levente]

hi,
i submit liboil as the first step to the gstreamer packages:
https://bugzilla.redhat.com/show_bug.cgi?id=490704
i leave in comment the original devel part in case we move to
static/devel subpackage in f12.
also we use 0.3.15 even though in rawhide only has 3.14 since it can't
compile on windows.
scratch build:

i hope someone can review it:-)
