RTEMS requires that the tools be configured and installed as targetting
RTEMS.  This is because of some minor things in gcc (multi-threaded 
safe library support being the big one) and major things in newlib.

You might be able to get by early on with --program-prefix=or1k- or
whatever
makes it point to the or1k tools.  But to compile a real existing target
like the pc386 BSP, you will have to have i386-rtems tools installed.
See ftp.oarcorp.com:/pub/rtems/betas/4.5.0-beta/c_tools/linux_x86 
(typed from memory so be warned).

Linux native compile uses native C library and header files.  This
is definitely wrong even though the code generator and object format
used are the same.
