>Description:
	make installkernel tries to write to /usr, it did not in 4.9-RELEASE.
	The change occured in revision 1.416 (and MFC 1.141.2.66)
	of src/Makefile.inc1. 

	The installkernel target is distinct target, not just a part
	of 'global system upgrade' and in my humble opinion there should
	be a way to install a kernel from /usr/obj/... without
	'make hierarchy' overhead. Think of read-only /usr. Think of
	installing a kernel over NFS. Think of very slow channels and
	of amount of transfered data.

	This change is some kind of regression.

>How-To-Repeat:

	With /usr mounted read-only:

# make installkernel
--------------------------------------------------------------
>Fix:

	Make an option allowing to install a kernel only - especially
	when MODULES_WITH_WORLD is defined.
>Release-Note:
>Audit-Trail:
>Unformatted:
 >>> Making hierarchy
