crosstool-ng/patches/gcc/4.2.1/300-libstdc++-nostdlib-linking.patch
Yann E. MORIN" ac159385fa Speaking of gcc-4.2.1, Ted Jordan writes on 20090401:
The generated libtool for building libstdc++ adds the -nostdlib option to the
 g++ command for linking but doesn't add -lgcc.  This causes a "hidden symbol"
 error when linking against the libstdc++ shared object.  This patch adds gcc
 to the list of libraries linked against when linking libstdc++.
