This change is intended to save time by not running bootstrap in
subdirectories unnecessarily. I see any time savings for bootstrap as
being useful; for my systems bootstrap takes as much or more time than
compiling rtems.

By the way instead of this approach I run bootstrap from the
subdirectory with the changes directly, e.g.
cd c/src/lib/libbsp/sparc
$r/bootstrap

where my bash environment has an environment variable r that points to
my rtems root directory.  However I see the patched bootstrap as also
being useful in such situations. It might also make sense to add some
error checking to ensure the base directory contains a configure.ac
file and to print some error if it does not, since bootstrap will not
work in a directory that lacks the configure.ac file.
