 I have this in my handy scripts for building rtems-examples:

CPU=powerpc
BSP=psim
./waf configure --rtems=${HOME}/rtems-work/tools/6/bsp-install \
                    --rtems-tools=${HOME}/rtems-work/tools/6 \
                    --rtems-bsps=${CPU}/${BSP}

That --rtems points to the --prefix directory you used when you built and
installed RTEMS.
This is from my install:

$ pwd
/home/joel/rtems-work/tools/6/bsp-install/sparc-rtems6/leon3
$ ls
lib  make  Makefile.inc

--rtems-tools directory should have a bin/TARGET-gcc under it.

--rtems-bsps looks OK

I think you have just pointed to the wrong directories. It should be
similar to
how I build rtems-examples.

Normally you don't point all the way down to share directory
