This is <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=25557>.
If this isn't a regression (which I'm not sure of), then I guess this

The relevant diff between branch-4_2 and branch-4_3 is this (which looks
a bit different from the patch proposed in that PR):

Try passing --enable-languages explicitly.
