I considered this but it requires adding another rpm spec
file and did not want to get involved in adding another
spec to the build right now.  

Long term, gdb will become more rtems aware so m68k-bdm
and m68k-rtems w/bdm support should be considered different.

This is not a bad idea and I think it is good step.

And James' comments indicate that a FreeBSD user could not
use a Linux gdb binary with bdm support in it.  So having
bdm and non-bdm variants is a better way to go.
