Good point.  TOPDIR is currently coded in bitbake:

./lib/bb/parse/parse_py/ConfHandler.py:    if not
bb.data.getVar('TOPDIR', data):
./lib/bb/parse/parse_py/ConfHandler.py:
bb.data.setVar('TOPDIR', os.getcwd(), data)
./lib/bb/build.py:        prevdir = data.expand('${TOPDIR}', d)

so, it won't be trivial to change without breaking existing build environments.

Thanks,
Cliff
