Any idea, how to fix it? libcgroup uses the same flag LIBS=-lfts.
Maybe the variable isn't propagated.
Or is the dependency expressed enough?

DEPENDS_append_libc-musl = " fts "
EXTRA_OEMAKE_append_libc-musl = " LIBC=musl LIBS=-lfts "

I'll have to put back patch
0002-kernel-controllers-Link-with-libfts-explicitly-on-mu.patch, but that's bad,
buildroot works without it.

Kind regards,
Petr
