PATCH COMMITTED: Fix section groups in objects with many sections

[Ian Lance Taylor]

Gold was not correctly handling section groups in object with many
sections, in the case where the object was created by a version of the
GNU binutils from before the fix for PR 5900.  I committed this patch
to fix it.  I added a template to the many sections test, which causes
the bug to appear.
