[rtems commit] m32r/m32rsim: Remove

Hi
FWIW when you delete the last BSP in an architecture the configure.ac in
libbsp/<ARCHITECTURE> needs to be looked at. It still referenced m32rsim.
It could also happen if the BSP is not the last one in the architecture if
we were unlucky.
I saw someone complain about a bootstrap error on irc overnight and this
could easily have been it. Although there are many other things that can
go wrong.
