gcc does not normally install libgcc_s.so.1 in /lib, so my guess is that
that file came from your OS, and your dynamic linker is finding it
before the libgcc_s.so.1 which was installed by gcc.  You could try
making it a symlink to the libgcc_s.so.1 which you installed.

Note that you can confuse systems by building and installing gcc into
system directories like /lib, overwriting the system libraries and
compilers.  It's often better to install gcc and use it elsewhere.
