One idea for this: just don't accept anything except the built-in
locales (C, C.UTF-8, POSIX) and absolute pathnames. For suid programs,
the latter could be rejected completely (the safest and probably what
we should do) or restricted to a set of reasonable paths where each
path component is checked for permissions.
Another idea is pulling the search path from /etc/musl-locale.conf or
similar. Obviously this is not the most friendly to Rune's usage case,
but it would just be one more hard-coded path to override in the
custom build, or if absolute pathnames were also accepted for locales
the support for /etc/musl-locale.conf could just be stripped out.
