I'm going to assume this is useful because you have some out of tree C++
plugins? I'd drop the last two patches for now until there is a slightly
more compelling use case.

The C++ compiler detection moved into meson in b485458e00 (configure,
meson: move C++ compiler detection to meson.build) so I don't think
there is currently a compelling reason to bring this back into
configure.
