Actually use timestamp file's timestamps so that things rebuild correctly.

Use ${TOOL_AWK} instead of ${AWK} or plain "awk" in make commands.
Pass AWK=${TOOL_AWK:Q} to shell scripts that use awk.

Verify that MAKEFLAGS contains "-j" before trying to manipulate it
with :C///.

pass the "-j" flag down to gmake. you can force -j option to
gmake by setting GMAKE_J_ARGS=-jN.
