The option substitution takes place before the files are installed. For 
example:

cat /opt/rtems/6/arm-rtems6/xilinx_zynq_a9_qemu/Makefile.inc
#
# BSP specific settings. To be included in application Makefiles
#
# This support will be removed from RTEMS. Please consider other
# ways to build applications.
