libgo patch committed: Update configure, a few binary files

[Ian Lance Taylor <iant at golang dot org>]

This patch to libgo updates the configure script and a few binary
files.  The configure script was changed without going through the
external repo in a way that somehow dropped the
--with-system-libunwind argument and made a few other changes.  This
patch restores these changes.  A few binary files were changed in the
external repo in merges from the master repo, but the changes did not
get reflected in the GCC repo.  These changes are all irrelevant--a
couple of "http" became "https" in files that appeared compressed but
were not actually compressed, and a couple of timestamps were zeroed
out in files that actually were compressed.  Patch bootstrapped and
ran Go testsuite on x86_64-pc-linux-gnu.  Committed to mainline.
