This could work but ...

Give me some time to pick at the bsp_specs. I have started a sweep to reduce
differences. There were spurious differences like spacing and some typos.

There are other issues to discuss that I want to discuss on the list. For
example,
"-e entry" and "-u undefined" are used in many bsp_specs. If we made a sweep
to move them all to the linkcmds, then that would be a good thing IMO.

On the PowerPC, we have rtems_crt[in].o and I don't know why we don't have
crt[in].o from gcc to use. That seems like something isn't right.

A number of relatively straightforward issues like that rapidly reduce what
happens
in the bsp_specs which makes it even easier to eliminate them.
