     2  The generated libtool for building libstdc++ adds the -nostdlib option to the
     3  g++ command for linking but doesn't add -lgcc.  This causes a "hidden symbol"
     4  error when linking against the libstdc++ shared object.  This patch adds gcc
     5  to the list of libraries linked against when linking libstdc++.
