Great. Is this with --enable-networking?

Is libbsd still not yet working?

I think so. You might try to write some simple script first for
yourself, to help think through the logic of automation.

Now that you know how to build by hand, you want to document what you
need to do and then you can try to script it. I'm not really sure, but
I guess it would be a new kind of "rtems-package" to build, since it
is done after rtems is successfully installed? We'll eventually want
this to be a vertically integrated package with the RTEMS
configuration combined with EPICS for some BSPs that are known to
work. Get started, and ask questions as you go.

work from doco at https://docs.rtems.org/branches/master/user/rsb/index.html
and submit changes as needed to improve it
