backport recent gold portability fixes to 2.23

[Roland McGrath <mcgrathr at google dot com>]

Attached is a series of five patches for the 2.23 branch.
Collectively they have the following gold/ChangeLog fragment.

This is straightforward backporting of those five changes I committed to
trunk yesterday.  Two of them required manual intervention, the others just
applied directly.  The gold.h change matches what's the system.h change on
trunk.  The relocate_for_relocatable change matches what's the
relocate_relocs change on trunk.

Ok for 2.23 branch?


Thanks,
Roland
