Bug#745547: pixman: Disable vmx for ppc64el architecture

["Breno Leitao" <brenohl@br.ibm.com>]

Package: pixman
Version: 0.32.4
Severity: wishlist

Dear Maintainer,

In order to be able to compile pixman on the ppc64el archictecture, the option
disable-vmx needs to be disabled at this initial moment.  So, this patch adds the
--disable-vmx option during the configure process.  

Thanks
Breno Leitao
