RTEMS vs. changing hardware: Building app against RTEMS build tree?

We are adapting RTEMS here to run our embedded control application on a
Virtex4 FPGA (or rather the integrated PowerPC core).
I am searching for relief from the "make all install" burden, which is
probably not neccessary anyway: Whenever I reconfigure the FPGA, I am
doing a rebuild of RTEMS and doing a make install.
However, for our application I would like to have a combined tree.
Currently, it is organized roughly as follows:
+ edk_repository (contains pcores and board definitions)
+ fpga_system (Xilinx XPS project with the hardware configuration)
+ rtems (contains the RTEMS source, currently 18.104.22.168)
+ b-rtems (build tree of RTEMS)
+ controller (contains the controller application, built against RTEMS)
After building RTEMS into b-rtems, I'll do a "make install", which
stores the whole thing into the prefix $HOME/opt/powerpc-rtems4.8. I
figure that I can just install it into a local directory rtems-install
but I'd rather just directly link against the build tree (which
obviously works for the testsuite).
Before I delve into the Makefile sources: Does somebody here already use
a similar setup?
Thanks and Greetings, Torsten
