I don't claim to have been following this thread, so no comments on
the notion of ${TOOLS_DIR}/bin/make ... though I gather its trying to 
cater for folk who put bare 'make' commands in makefiles?

Anyway, the above looks rather expensive.  How often will this be invoked?
Once per-package?  Why not at least put an .if !exists(${TOOLS_DIR}/bin/make)
in there to avoid running awk.
