is adding new private symbols to libc frowned upon?

[Yuri Pankov]

Essentially, I need the __collate_equiv_value symbol to be visible to
libregex for the changes in https://reviews.freebsd.org/D18531.  Is the
following change OK (it works, at least), or should try to avoid that?

--- a/lib/libc/locale/Symbol.map
