When you invoke either clang or gcc with -E, files with unknown
extensions are not preprocessed, and considered to be linker input
files.

When you invoke clang-cpp or cpp, files with unknown extensions are
considered to be C instead.

Since our RPC-related files use the .x extension, -E doesn't work as
expected, and the resulting files will give a compile error later on.
