prom-libc test rig

[Remco Treffkorn <remco@rvt.com>]

In order to see what's missing, I added a 'test' target to the Makefile. That 
would compile test.c to test.o and then link it with libc.a. Naturally _start 
was missing, so I added crt/Crt0.c and linked that in.

With the formalities out of the way, everything missing still, is what needs 
to be added. Since test.c is basically "hello world", write is one of the 
expected missing functions. The missing __progname in assert.c I added to 
Crt0.c.

The few things that bother me are that stdin, stdout, and stderr are missing. 
These belong to stdio, and not in the kernel.

Also vsnprintf wants __udivdi3 and __umoddi3. These are probably gcc support 
functions. I don't know where they normally are, but I know how to find  out.

My goal is to be able to link against prom-libc as a replacement for glibc in 
order to be able to test it.

Is there any merit in what I am doing, or am I wasing my time?

Cheers,
Remco
