    libstdc++: Add module initialization functions to the library [PR124268]

    This ensures that the module init functions are present in libstdc++.so
    and libstdc++.a, so that users of the std and std.compat modules don't
    need to manually link to std.o and/or std.compat.o in addition to
    compiling the CMIs.

    This also adds a clean-local target to remove the generated interface
    units and manifest, and the gcm.cache directory for the CMIs.

    libstdc++-v3/ChangeLog:
