Bug 22256

	I'm not really sure which category this belongs in; 'bin' seems
	to be the likeliest bet. Apologies if this is in error.

	To remake world on #2, it is first built on #1 as compliation time
	is far too long and available memory probably isn't up to the job.

	'make world' was previously run on machine #1 with CFLAGS options
	'-march=i686 -mcpu=i686', for obvious performance reasons.

	Before performing 'make buildworld' with machine #2 as the intended
	target system, these options were changed to '-march=i386 -mcpu=i386'.

	The installation is performed in the following stages (assume
	single-user mode for machine #2):

	1.  a 'make buildworld buildkernel KERNEL=DINO' is run on machine #1.
	2.  /usr/src and /usr/obj are NFS-mounted onto machine #2.
	3.  'make installkernel KERNEL=DINO' is run on machine #2.
	4.  'make installworld' is run on machine #2.

	In the case above (which is admittedly rare), this results in a
	Signal 4 (Illegal Instruction) during 'make installworld' when the
	'strip' command is called (notably by 'install with the '-s' option)
	as 'make installworld' will attempt to use the broken binaries in the
	/usr/obj/usr/src/i386 tree.

	I suspect that that is happening during build time is this: a number
	of static binaries in /usr/obj/usr/src/i386 are being linked with the
	(possibly older, or even incompatible) libraries resident in /usr/lib
	at the time the build took place, rather than the newly-compiled
	libraries in /usr/obj. I suspect therefore that this is a bug in the
	'make buildworld' process.

	This may affect other binaries used during the install process (though
	I must confess I didn't notice any problems with any of the others).
	It is not expected to affect any binaries on the target system once
	installation is complete, as the new binaries will be (dynamically
	or statically) linked with the correct libraries during the
	installation process (they are not statically linked during the
	build process).

Fix: 

The workaround is to copy the existing (static) 'strip' command
	from Machine #2's /usr/bin to /usr/obj/usr/src/i386/usr/bin prior
	to performing 'make installworld'.

	A permanent fix may be to include 'strip' in the list of files to be
	copied to '/tmp/install.NNN' (where NNN is the PID) during the install
	phase, and remove it from the list of static binaries built in
	/usr/obj/usr/src/i386 during the build phase.
How-To-Repeat: 
	See above. (You'll need two machines, I suspect.)
