Ok, what kind of time frame are we looking at? Within the 2016.11 cycle
or longer?

git grep -A3 STRIP_none package/Makefile.in
package/Makefile.in:ifeq ($(BR2_STRIP_none),y)
package/Makefile.in-TARGET_STRIP = true
package/Makefile.in-STRIPCMD = $(TARGET_STRIP)
package/Makefile.in-KSTRIPCMD = $(TARGET_STRIP)
So the stripping in target-finalize becomes a NOP when BR2_STRIP_none is
selected.
