gold patch committed: Permit assignment to dot outside of SECTIONS

[Ian Lance Taylor]

The Linux kernel build uses linker scripts with assignments to the dot
symbol outside of the SECTIONS clause in order to implement asserts.
Although an assignment to dot outside of SECTIONS, apparently this was
required in order to use assertions in older versions of the GNU
linker.  The GNU linker essentially treats assignments to dot outside
of SECTIONS as though they occurred within SECTIONS.  I committed this
patch to make gold act the same way.

	dot assginment to script_sections_.
