Maybe I should have given more detail on the chain of events.
You got most of it.  The missing piece is:

m3-libs/libm3/src/m3overrides contains:
_M3BUNDLE_OVERRIDE = "T"

So, 'do-cm3-*.sh build' runs 'cm3 -build -override', causing the
above file of quake code to be interpreted, defining _M3BUNDLE_OVERRIDE,
and the rest is as you have noted.
