There are a handful of issues here.  With RTEMS you are normally
cross compiling so you have to specify a target (--target=CPU-rtems)
and a BSP (--enable-rtemsbsp=BSP).  For example, i386-rtems and pc386
or sparc and erc32 are valid combinations.

I would not recommend using --program-prefix and --prefix. Use only
--prefix.

And install RTEMS where the tools are (/opt/rtems).

See the README in the hello world.  RTEMS_MAKEFILE_PATH is normally
something like /opt/rtems/BSP.  You export that to point to your
installed BSP and type make.
