Enable the sc_texinfo_acronym check

* cfg.mk: Enable the sc_texinfo_acronym check.  Exempt
doc/perm.text, which isn't ours anyway.
* doc/find.texi (Deleting Files): Say just POSIX rather than
@acronym{POSIX}, simply because this is the convention in GNU
documentation.  The motivation is that it's hard to do so
consistently (because, for example, you can't use @acronym in a
node name).
