preprocessor-collate

Allow preprocessor-like directives.  These keywords were already
defined in locale/programs/locfile-kw.h, an implementation for
'define', 'undef', 'ifdef', 'else' and 'endif' is now provided in
locale/programs/ld-collate.c.  For the moment, 'ifndef' and 'elif'
are not implemented because they do not appear in locfile-kw.h.
This patch is harmless, it only adds new keywords.
