I felt lucky fixing the sim rules.  I think you blew all your
rounds on the sim/common changes. :-)

Before, a failure in any of the sim subdirs didn't stop
compilation.  I think you saw that too, yes?  Noticed when
letting the --enable-cgen-maint build the generated C files (but
somehow the rules can't really cope with non-existing generated
files, so something like 1+2*#cpu-variants rounds is needed).
When doing that, compilation just continued on, building gdb,
then running the sim test-suite (oops! have to submit & commit
that too) but failing to find the simulator.

I checked briefly that all the rules would be present in the
subdirs, which would possibly be an arguably valid reason to not
fail when the subdir make fails.

	(realclean, install): Fail if subdir make failed.
