sparc64 linker scripts get installed and removed during upgrade

I have a sparc64 host running stable/10.

I have noticed on the last several updates that I've
done (basic list of operations below):
	checkout current stable/10 sources
	make buildworld
	make buildkernel
	make installkernel
	reboot
	mergemaster -p
	make installworld
	mergemaster
	make delete-old

I get a bunch of sparc64 linker scripts that get installed
each time, and then are removed during the 'make delete-old'
operation.

root_at_gatekeeper-372: make delete-old && make delete-old-libs

I would think these shouldn't be installed at all, if they
are not needed or obsolete.

Thanks.
