[DRE-maint] Bug#1148247: ruby-gnome: disable webkit support on big endian architectures

Hi,

webkit2gtk is being removed on big-endian architectures since upstream
has dropped support there. Please stop build-depending on webkit and
building the webkit binary package on those architectures.

Cheers,
Emilio
