#     kbuild: ensure Make >= 3.82 is used
#     
#     Documentation/process/changes.rst notes the minimal GNU Make version,
#     but it is not checked anywhere.
#     
#     We could check $(MAKE_VERSION), but another simple way is to check
#     $(.FEATURES) since the feature list always grows.
#     
#     GNU Make 3.81 expands $(.FEATURES) to:
#       target-specific order-only second-expansion else-if archives jobserver check-symlink
#     
#     GNU Make 3.82 expands $(.FEATURES) to:
#       target-specific order-only second-expansion else-if shortest-stem undefine archives jobserver check-symlink
#     
#     To ensure Make >= 3.82, you can check either 'shortest-stem' or
#     'undefine'.
#     
#     This way is not always possible. For example, Make 4.0 through 4.2 have
#     the same set of $(.FEATURES). At that point, we will need to come up
#     with a different approach.
