[rescue] compiling sunos4 sources

[Dan Moisa]

Thanks for the offer. I have no RULES file, there's some thin readme that
doesn't help.
I see "populate", "makelinks" and "mkinclude" that all fail at various
stages. If you have instructions that get me to "make" in either sys/os or
sys/boot without errors then that's a start. I could also use a system
image I can just extract. I can give you a dump of the file system.
Whatever is easier for you.

The goal is to add some debugging statements in sys/os/init_main.c. main
function. I get hung up somewhere after dumpinit(); and before
kern_proc(icode1, 0); can properly execute and get into init. I can tell
because I can compile init with debug and test on an original, but because
it's smaller with fewer deps. I can't compile this part of the kernel
without errors, and it seems to be one of the objects that gets loaded up
in the regular config/kernel configuration. If I got the path here wrong,
please let me know.

In the longer run I need to also figure out how to compile a boot prom with
tweaks, but that can be a different thread.

Thanks again,
Dan.
