I agree this is rather unhelpful.

I suspect no one has looked into it. If you know autoconf and automake 
and you are able to find a solution please post a patch.

The complexity as I see it is the initial configure phase does not check 
the BSP list and the configure is spread across the initial configure 
and further nested configures in the make phases so when do you check. 
To check for the BSP you would need to check for a valid .cfg file in 
the correct arch. Maybe the rtems-bsps script could provide some hints.

FYI there is an active project at the moment to move to a waf build 
system for RTEMS. The plan is to release 4.12 and then switch the master 
branch to waf.
