AC_CHECK_LIB(crypt, crypt) will automatically add -lcrypt to $LIBS. It
will also define HAVE_LIBCRYPT (is this what you're trying to avoid)?
Anyway, I'd prefer:
  AC_CHECK_FUNCS(crypt, , AC_CHECK_LIB(crypt, crypt))

This way we check if crypt is resolvable using the existing $LIBS and,
if not, use $LIBS+-lcrypt.
