Subject: [PATCH] build-libcxx: Install the libc++ module in a shared directory

By default these files would be installed into
${CMAKE_INSTALL_PREFIX}/share/libc++/v1, where
${CMAKE_INSTALL_PREFIX} is equal to ${PREFIX}/${arch}-w64-mingw32.

However, to avoid duplicating these files for each architecture,
install them into ${PREFIX}/share/libc++/v1 instead.

While the files aren't very large (currently weighing in at around
612 KB), they're architecture independent files (and they're
more than a few; they're currently 135 files), so we should
share them if possible.
