- Determine KERN_AS automatically depending on whether OPT_MODULAR is
set or not, in the same way as libcompat.

- Specify OPT_MODULAR in the port Makefile instead of KERN_AS.

Now, KERN_AS=library is used for kernels without module(7) for all ports.

OK christos

branches: 1.28.36;
Explicitly set KERN_AS (this could be done in /usr/src/sys/conf/Makefile.*)
so that modules work, on config files that did not set it explicitly. All
the files now use the standard logic, except the ones that set KERN_AS=obj
and Makefile.usermode which sets KERN_AS=library.

Default COPTS to "-Os -freorder-blocks" which is ~= -O2 but without
-falign-* that is too zealous for low-memory sh3 machines. I've been
using this for my hpcsh and landisk kernels for a very long time.
(besides, it's not 2001 anymore and pkgsrc/cross/sh is long since gone).

G/c ancient workaround that has been commented out for ages.

There's no reason to use -Wno-parentheses.

Stop using linker scripts on all sh3 ports.

The only information to be compensated is text section start address.
The default value is set arch-wise as DEFTEXTADDR. Each kernel config
can override the default value by setting TEXTADDR.

Tested on COMPUTEXEVB (evbsh3).

cosmetic changes, fix comments.

Move common exception vector and scheduler code to
sh3/sh3/exception_vector.S and sh3/sh3/locore_subr.S. exception
vectors are installed by sh_cpu_init(). machine/locore.S contains
kernel entry, interrupt handler, and some MD code.

Roll the rest of the ports over to the new MI kernel build machinery.
Any problems reported by testers have been fixed, and massive
cross-compiling of kernels has shown that any problems that remain
with actually building kernels are not related to this.

cleanup:
options SPACE TAB
makeoptions TAB
psuedo-device TAB
remove trailing whitespace
replace multiple spaces -> tabs
options "FOO" -> options FOO
options "FOO=bar" -> options FOO=bar
options "FOO=\"bar\"" -> options FOO="\"bar\""

Change defaults for kernel compiles. Default all to USETOOLS?=no and have
the etc Makefile override that by putting USETOOLS into $.MAKEOVERRIDES
This way the default for kernel compiles is still to use the installed
toolchain instead of depending on $TOOLDIR. $TOOLDIR can be used by
simply adding USETOOLS=yes to the command line as usual.

Adjust each ports template to set the default no setting and also pull in
bsd.own.mk if they weren't already to ensure they'll build correctly
with the new toolchain setup.

Add "install" target, so "make install" after building the kernel
does something useful. The target can be redefined by putting a
install-kernel-${MACHINE_NAME} target that fits your needs into
/etc/mk.conf.

HAVE_GCC28 -> HAVE_EGCS, and make it match gcc 2.9 as well. Also,
make the use of -Wno-uninitialized explicit, don't rely on a compiler
hack to do it for us.

Revert STRIPPROG -> STRIP

Add "dependall" target for comfort.

Merge in NetBSD/sh3 from cvs.kame.net repository.

Tree structure:
- sys/arch/sh3: sh3 generic code
As commented, in-chip device drivers are put into sys/arch/sh3/dev.
- sys/arch/evbsh3: sh3 evaluation boards (pure sh3 CPU, no fancy external HW)
- sys/arch/mmeye: Brains mmEye, www.brains.co.jp
MI source code includes couple of #ifdef for sh3-coff support.
(sh3 uses coff or elf)

Needs some more improvements, especialy in sys/arch/sh3/conf/files.sh3,
to compile the tree (due to last minute tree structure change).
