We compile it on the given platform so we need some way to support all 
at once.

For example, the code that builds fine on F-11 fails like this on F-9:

Compiling targeted ipa_webgui module
/usr/bin/checkmodule:  loading policy configuration from tmp/ipa_webgui.tmp
ipa_webgui.te":77:ERROR 'syntax error' at token 
'userdom_dontaudit_search_admin_dir' on line 10764:
userdom_dontaudit_search_admin_dir(ipa_webgui_t)

The diff between F-11 and F-9 being:

-userdom_dontaudit_search_sysadm_home_dirs(ipa_webgui_t)
+userdom_dontaudit_search_admin_dir(ipa_webgui_t)
