This is a very, very old problem.  ISTR, wrong autoconf macros used to
test for htole* &co, but last time I looked I decided I don't have
enough of autoconf fu to fix it properly and it doesn't really bother
me that much.

Since we provide re-implementation anyway, the easiest way is to alway
use out own version, I'd guess.
