We don't need any special CFLAGS/LDFLAGS for libiberty. What we do need
is any CFLAGS or LDFLAGS set by the user, for example -I or -L to point
to libraries and include files in custom paths. In all the other
test-*.bin rules in build/feature/Makefile, we use the BUILD macro which
always sends in CFLAGS and LDFLAGS. The libiberty build line doesn't
use the BUILD macro and thus needs to send in CFLAGS and LDFLAGS
explicitly.

So FEATURE_CHECK_CFLAGS_libiberty doesn't seem like the correct thing to
use, since that would imply that libiberty needs some special flags?
