libstdc++.so* is needed by some applications during build,
including gnome-mplayer.
This recipe copies the shared library from the crosscompiler
directory, without having to install the complete compiler
in the target system

Checking in a non-external-toolchain based build I have around, I see
staging/<target>/usr/lib/libstdc++.so / libstc++.so.6 which point at
libstdc++.so.6.0.10, which exists. Can you explain how you're getting a
lack of libstdc++? Thanks.

I assume he is using gcc to link and some external lib linked C++ symbols into
the global scope... This was a bug in some versions of gcc and we solved it in
WebKit/GTK+ by having a linker script and excluding everything _Z*.
So I would nack this change and instead figure out which C library is exposing
C++ symbols.

I think we have had discussions about packaging gcc runtime. There
were some proposals on packaging it
but the directions seems to be that we need to package them better.
Weather we create a single package
for all runtime or package each language runtime differently is
decision to me made. I think toolchain-desuck
branch would be the right place to get this done.

I can also see this in the target but it is needed also during the build
of gnome-mplayer, or that will fail.

When building gnome-mplayer, it complains that "libmusicbrainz"
needs the symbols from libstdc++.so.6.

Which symbols? Please mail us the link error. In any case the compile/link fix
is more inside libmusicbrainz than it is in copying the libstdc++ around.
