Hmm, 7.5KB isn't much - But fts isn't enabled by default in uClibc-nc,
it is a legacy BSD feature and it also isn't supported by musl.

It is easy to enable uClibc options, but difficult to disable them again
later (as users of the affected packages get caught).

Looking around, it seems we are only talking about 3 packages (if the
annotations are correct):

git grep -l 'fts.h' **/Config.in
package/libcgroup/Config.in
package/libselinux/Config.in
package/libsemanage/Config.in

Do we care enough for selinux users on uClibc (libcgroup seems to only
be an optional dependency for gst1-rtsp-server) to let all other
uClibc-ng users pay?
