Add the static lib in the check, in case only the static version
is available.

What we really want to know is two-fold:
  1) are requirements for PPL available?
  2) can we build a statically linked toolchain?

Which trnslates into:
  1) is libstdc++ available at all (shared or static)?
  2) is static libstdc++ available?

Yes, this could duplicate the test below. We don't care, as most of
the time, the shared library will be present, and thus the two tests
will be different.

This hunk should go into the patch 2.
