In sys/<arch>/conf/Makefile set TARGET to <arch>. That allows
sys/conf/makeLINT.mk to only do certain things for certain
architectures.

Note that neither arm nor mips have the Makefile there, thus
essentially not (yet) supporting LINT. This would enable them
do add special treatment to sys/conf/makeLINT.mk as well chosing
one of the many configurations as LINT.

This is a hack of doing this and keeping it in a separate commit
will allow us to more easily identify and back it out.

Discussed on/with: arch, jhb (as part of the LINT-VIMAGE thread)
MFC after: 1 month

Implemented "nooption" and "nomakeoption" config(8) tokens.
Fixed memory leak in the "nodevice" option implementation.

Use these instead of sed(1) in MD NOTES.

Use a single makefile (sys/conf/makeLINT.mk) to generate
LINT for all architectures. (Previous versions missed
the LINT dependency on Makefile, and i386 version also
missed the dependency on ${NOTES}.)

Fixed bugs in the previous NOTES conversion using the
"nodevice" token and sed(1):

- i386 LINT lost "device pst".

- pc98 LINT lost SC_*, MAXCONS and KBD_DISABLE_KEYMAP_LOAD
options, and got needless DPT_* options.

- Added nooptions PPC_DEBUG, PPC_PROBE_CHIPSET, KBD_INSTALL_CDEV
to sparc64 LINT so that it has a chance to config(8).

This basically returns us to where we were before.

Move most everything back to a MI NOTES, and use "nodevice" in MD NOTES
Where needed. Use 'sed' for now in place of "nooptions". Add a sparc64
MD NOTES.
