[Buildroot] [git commit] gstreamer: Allow libxml2 dependency to be configured.

[Will Newton]

commit: http://git.buildroot.net/buildroot/commit/?id=9310e12d5bbb5e10f899672980fb63bd24382bd1
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master


gstreamer uses libxml2 to support the plugin registry and pipeline
load/save features. This change allows the user to build gstreamer without
libxml2 which saves a large amount of space on the target.

Closes #373.
