I was wondering for a while, if we really need both options in autotools.

Esp. since to use a custom loader one needs to
LD_PRELOAD/LD_LIBRARY_PATH it already.
Thus adding the LIBGL_DRIVERS_PATH is trivial, either way.

The following approach is a bit shorter and easier to read.

dri_search_path = get_option('dri-search-path')
iif dri_search_path == ''
  dri_search_path = dri_drivers_path
endif
