I suppose we don't.  One way to find out would be to commit just this
bit

+# We need the $(eval) function, which is available in GNU make 3.80.
+# That also happens to be the version where the .VARIABLES variable

+ifndef .VARIABLES
+$(error GNU make 3.80 or newer is required)
+endif

with a $(warning) instead, and let it run for a bit.
