Disable AC_PROG_CXX and consequently a libstdc++ dependency for libffi,
introduced with upstream libffi commit 7d698125b1f0 ("Use the proper C++
compiler to run C++ tests"). This is only needed for the libffi test
suite, which we don't have to support in the GCC tree, as libffi is
maintained as a separate project. The dependency causes a build failure
with the `powerpc64le-linux-gnu' target due to a circular dependency:
make[1]: Circular configure-target-libffi <- maybe-all-target-libstdc++-v3 dependency dropped.
make[1]: *** [configure-target-libffi] Error 1
make: *** [all] Error 2
due to a libgomp dependency for libstdc++ and then a libffi dependency
for libgomp, introduced with commit 998eb38b265d ("Use functional
parameters for data mappings in OpenACC child functions").
