waf bsp_defaults appears to be broken

I would not use the the bsp_defaults approach to handle BSP testing. The BSP
defaults build target should only be used as a means to find and examine any
options a BSP may have you wish to override. Capturing defaults is counter to
the notion of defaults, ie defaults change?

If you wish to use the defaults then this is all you need:

 $ echo "[powerpc/psim]" > config
 $ ./waf distclean configure build

If you what to build the tests, POSIX API and debug on:

 $ echo "[powerpc/psim]" > config
 $ echo "RTEMS_DEBUG = True" >> config
 $ echo "RTEMS_POSIX_API = True" >> config
 $ echo "BUILD_TESTS = True" >> config
 $ ./waf distclean configure build

In regards to removing build directories and others things in the lengthy thread
attached to the email, user beware. The recommended solution is:

 ./waf distclean
