[packman] x86-64 Factory builds

[Cristian Morales Vega]

Any idea about what's the problem with the x86-64 Factory builds? They
fail a lot with "internal compiler error" messages but the same build
works with every other distro, with the i586 Factory build and even
with the x86-64 Factory build in the main OBS. For an example see
http://pmbs.links2linux.org/package/show?package=moc&project=Multimedia
vs https://build.opensuse.org/package/show?package=moc&project=home%3ARedDwarf:multimedia
