Update libgo/configure to restore it to the master version.

Update a few binary files that were changed in the master gc repo,
copied into the gofrontend repo, but not correctly copied into the GCC
repo.  The changes are all minor and do not affect any actual tests.
Two instances of "http" changed to "https", and two timestamps were
zeroed out.
