You could optimize this further - at least from the top level, by
noting that WRKOBJDIR is of that form, and simply: rm -rf ${WRKOBJDIR}/*
I use that model for a top level 'destroy' target (different project) 
that is at least 3 times faster (including the subsequent 
'make obj' pass) than doing 'make clean'.
