This patch has same changes as one I sent to you earlier plus
it fixes _heap_size problem for pc386 we had discussed earlier.
Now, _heap_size is defined and set to 0 in pc386/startup/bspstart.c
It can be patched to desireable value in binary image. If it is
left unpatched, then startup code will determine size of memory
(on the assumption that at least 2MB are present) and use
max possible heap.
make solaris target buildable.

BSDINSTALL is defined in make/host.cfg.in as
BSDINSTALL=@INSTALL@
@INSTALL@ is generated by autoconf's standard macro AC_PROG_INSTALL, which
is widely used in almost any autoconf/automake configured package. In case
there is really something wrong with it, then it must be considered a bug
in autoconf.
I can see a doubious fragment in AC_PROG_INSTALL, which is used when no
appropriate bsd-install is found.
Finally Ralf saw a problem with the find on solaris which I also saw and
fixed.
Here is a small patch which allows the m68060 to be used. I have not
tested the FP switching stuff which we know is broken. This is taken
against the libchip snapshot but should merge without problems. If you
have any problems please let me know.
There are other smaller issues such as superscalar enable and cache
control which I have not addressed yet. They are different to all other
m68k processors. These can wait IMO.
