Automate file and symlinks copy for libstdc++
Automate file and symlinks copy for libstdc++

Previously, libstdc++ files and symlinks were specified in a list,
which could get stale and break (encoded version numbers change).
This changes switches to using a patern match for libstdc++ and
libsubc++ to ensure actual files get copied.
