Actually the default in bmake distribution is false which is 
the backwards compatibile behavior.
Makefiles like my dirdeps.mk force it to false just in case since it
depends on that behavior.

The default in NetBSD is true, I expect someone changed
pkgsrc/devel/bmake to true to match NetBSD.

As noted above Makefiles that care can set the value they want,
but that can be hazardous if *mk depend on opposite behavior.
