[Chris Johns]

Hi,

/opt/work/chris/rtems/kernel/rtems.git/configure \
  --prefix=/opt/work/rtems/bsps/5 \
  --target=sparc-rtems5 \
  --enable-rtemsbsp=leon3 \
  --enable-posix \
  --enable-networking \
  --enable-multiprocessing \
  --enable-tests \
  --enable-maintainer-mode

fails with:

gmake[6]: Entering directory
'/opt/work/chris/rtems/kernel/bsps/arm/sparc-rtems5/c/leon3/lib/libbsp/sparc/leon3'
gmake[6]: *** No rule to make target
'../../../../../../bsps/shared/shmdr/shmdr-shmisr.c', needed by
'shmdr-shmisr.o'.  Stop.
gmake[6]: Leaving directory
'/opt/work/chris/rtems/kernel/bsps/arm/sparc-rtems5/c/leon3/lib/libbsp/sparc/leon3'

This worked before the last set of changes ...
