GCC: libstdc++ has a link to libiconv
After adding the libiconv library to the template, the C++ library uses
three of its functions (`libiconv', `libiconv_open' and
`libiconv_close'). However, it doesn't explicity link with it inside its
shared library!
I tried by exporting `LIBS=-liconv' before the GCC configure script but it
crashed as soon as it went on to the second GCC building stage (because
this environment variable was no longer present there). I also tried adding
the C++ configure option of `--enable-cstdio' to the GCC configure options
(so it doesn't use iconv according to the manual), but it made no change.
With this commit, as a brute-force solution, `patchelf --add-needed' is run
on the installed `libstdc++.so', so `libiconv.so' is explicitly included
inside the `libstdc++' shared library.
This bug was found by Roberto Baena Galle while trying to load Matplotlib
(which needed the C++ library).
This fixes bug #56702.
