How official do we want this to be? Currently it is disabled by default, but if
we want to have it enabled by default this should be changed to use pkg-config
to find the library (add a target to build/linux/system.gyp) and
build/install-build-deps.sh needs to be updated to add libgbm as a dev
dependency.

it's more work but if we're going to have this code in tree for the present
(which seems like a good idea) then doing the above work is a good idea.

[vignatti (out of this project), 2014/05/27 16:40:20]

But can we have gbm discovered by pkg-config at least?

PS: awesome to see this CL going through.

Done.
