Link requires __eabi with different gcc

Ralf, thank you.
Yes, I am doing a thing a bit weird...:-))
I have a working demo project for mpc8247 under cygwin.
I took the project directory AS-IS and try to receive the same result under 
Linux and RTEMS tool chain. So, I use the original makefile and sources.

This was how they did this...
OK, I changed to gcc. The error is:
undefined reference to `_SDA_BASE_'
undefined reference to `_SDA2_BASE_'
collect2: ld returned 1 exit status

I searched all the rtems4.7 tarball - no reference to these variables in any 
linkcmds file.

Well... tool chain is RTEMS 4.7. Everything is compiled from sources... What 
and where can be else?
