libgcc_s.so.1 must be installed for pthread_cancel to work

I like these answers. :-)

gcc 4.x compiled with:

--enable-shared=libstdc++
--enable-static
--disable-debug
--enable-cpp
--enable-languages=c,c++
--enable-threads
--enable-symvers=gnu

This combination doesn't generate shared libgcc_s library, only static.

With this compiler glibc configure doesn't complains about the missing
libgcc_s library.

Now its clear libgcc_s.so required for modern glibc, the question is,
should I move to gcc list complaining, or glibc configure should check
for this "broken" gcc install?
