If you have your cross compiler toolset all correct shouldn't the error be
something
like this -

/opt/rtems-4.11/bin/../lib/gcc/i386-rtems4.11/4.5.0/../../../../i386-rtems4.11/bin/as:
unrecognized
option '-mcpu=arm920t'

One possibility is that you may have not installed the binutils part of the
cross compiler toolchain.
