Good advice, I'll have to remember that.

I ended up building:
	- ld
	- as
	- gcc
	- compile_et
	- make_cmds
	- libc
	- sh

and after that it died.  Everything I ran with sh would dump core
after returning from the exec (dowaitproc or something is where
it died).

Caught it before I rebooted my system, restored the old sh (always keep
a backup sh around), and built a kernel successfully and rebooted.

But then ldconfig caught the new libc which kept on dying with
"SYS_getdents() undefined in libc.so.12.19".

Got rid of libc.so.12.19 and everything is fine again.  Now I need to
rebuild libc and try again.

 * 
 * I also build all my kernels with COMPAT_12, which helps ease these
 * transitions.

I think I've got compat all the way back to 1.1.  Plus 4.3.

Has the problem been fixed so that I don't need COMPAT_43 to make
ttyname(3) not return ENOTTY?
