Bug#751259: webkitgtk FTBFS on armel/armhf

[Riku Voipio]

Package: webkitgtk
Version: 2.4.3-2
Severity: serious
Justification: FTBFS

Hi,

It seems libgl1-mesa-dev will be pulled in regardless:

dd-schroot-cmd -c sid_armhf-dchroot-7101d185-7aa9-42e0-a68c-0bbf3271b410 apt-get build-dep webkitgtk
...
  libgirepository-1.0-1 libgirepository1.0-dev libgl1-mesa-dev libgl1-mesa-glx
  libglapi-mesa libgles2-mesa libgles2-mesa-dev libglib2.0-0 libglib2.0-bin
...

So a build-conflicts: libgl1-mesa-dev [armel armhf] would be needed, or the sources
need to accomodate the possibility of both installed. Since with freeadreno and nouveau
drivers coming to arm, there are also full opengl drivers for arm, this kind of arch based
detection is a bit frowned upon.

If armel/armhf go gles, please check that all packages building upon webkitgkt still work
on arm after the change.
