build problem on Ubuntu

I just built RTEMS-4.10 on my Ubuntu 11.04 system. I followed the 
"getting started" instructions for Debian-based releases and all of the 
packages converted OK using alien. When I came to building, I got the 
"compiler can't create executables" error. THe guide tells me to install 
the libc-dev package. On investigating, Ubuntu has libc6-dev, which was 
already installed. So I tried to compile a simple "Hello world" program 
free-standing, using:

m68k-rtems4.10-gcc -c hello.c

It failed, complaining about not finding two libraries. I committed the 
following sins:

In /usr/lib/ I did

ln -s
ln -s

After that, hello world compiled, and the full rtems build completed 

What should I have done?
