don't create a broken urn-gtk.h if xxd fails #7

Closed codl closed 9 years ago

codl commented 9 years ago

if xxd is not installed, or if it is broken in some way, the build will fail when creating urn-gtk.h but an empty urn-gtk.h will still be created and this step will be skipped on further attempts to build, even if xxd is now functional

this removes the broken urn-gtk.h file if xxd failed
