the Blackfin GDB from http://blackfin.uclinux.org/ doesnt have any BSP
specific aspects to it.  it does have part specific info though
(BF537).

the error message indicates usage of a Blackfin GDB port from before
our complete rewrite to support a full operating mode.  i have no idea
how the RTEMS website source tree corresponds to the sources at
http://blackfin.uclinux.org/ or the FSF versions.  although the FSF
gdb does not yet support Blackfin parts which means any RTEMS tree has
been patching it in ...
