cxref fails to cross build from source, because the configure script in
the cpp directory uses AC_TRY_RUN without a cross compilation
alternative. However, that particular check doesn't actually need to run
as all it tests are compile time constants. It can be turned into a
AC_TRY_COMPILE. Please consider applying the attached patch.
