ext/-test-/cxxanyargs: prevent have_devel check
The `cxx.try_compile` command in this file kicks `cxx.have_devel?` internally, which recursively calls `cxx.try_link` with a different source code. We don't want that happen (the source code compiled in this file must be the first one). We need to fake the system.
