This looks like bug 16915 has come back again.

It was fixed in 2.20, and a testcase covered this e.g. tst-langinfo compiled
static... oops, but there were no LC_MONETARY entries in the data input for
this test :-(

It looks like the static build is still optimizing out what it considers unused
categories. So the fix is incomplete.
