The i386-rtems-gcc target is more than just a compiler to generate i386
code.  It includes
information about the target OS for run-time information (thread-safe
C++ STL for example)
and the newlib C Library configuration is specially tailored for RTEMS. 
So the target i386-rtems-gcc
is not what you want.

Follow that can I use an embedded i386 GNU tools configuration.  The
answer is "it depends".
What object format is the code using?  What C library are you going to
use?  Should the
generated code be flat-mode or some special 48 bit segment:offset
setup?
