Log Message:
make: allow to randomize build order of targets

In complex dependency structures, when a build fails, a probable cause
is a missing dependency declaration between some files.  In compat mode,
the build order is deterministic, in jobs mode, it is somewhat
deterministic.  To explore more edge cases, add the line ".MAKE.MODE +=
randomize-targets" somewhere in the makefile.
