Are you using the RTEMS versions of automake/autoconf or what came
with the system?

Yep.  bootstrap works in any directory with a configure.ac script in it.

I don't know.  I don't use it often.  When I do full builds of all
configurations, I bootstrap -c / bootstrap from the top as the 
first thing.
