Description of problem:
Cups doesn't use %find_lang for locale.
This will make the package incompatible with the %_install_lang macro which
allow to only install the desired locale

Version-Release number of selected component (if applicable):
all version until current.


How reproducible: always


Actual results: cups only install a .po file into %{_datadir}/locale/%lang 
and load it via cups/langage.c
see l.717     
snprintf(filename, sizeof(filename), "%s/%s/cups_%s.po", cg->localedir,



Expected results: cups should use gettext to properly build localization and the
rpm spec file will have to use the %find_lang macro once done.



Additional info: the current svn version doesn't have any improvement about this
question.
