xscreensaver: why are glx hacks disabled?

[argosphil]

I stumbled across this while playing with OpenGL on an embedded device:

meta-openembedded/meta-oe/recipes-graphics/xscreensaver/files/0002-build-Do-not-build-po-files.patch

Lines 26 to 29 in c1dd0ff

	-SUBDIRS = utils jwxyz hacks/images hacks hacks/glx hacks/fonts \
	- driver po
	+SUBDIRS = utils jwxyz hacks/images hacks hacks/fonts \
	+ driver

The commit removes the hacks/glx directory without explanation. Was that by mistake? I've tried and while the recipe needed some adjustment in my case, the GLX hacks work fine once reenabled by undoing part of that patch.

@argosphil its an oversight, only po generation is supposed to be removed by this patch. Can you submit your changes to this patch to re-enable glx hacks a PR
