Good work at bisecting it! :-)

This is indeed a change in behaviour. However, as make ever documented
a guranteed/non-guaranteed ordering of wildcards to begin with?

The manual for the current make version says nothing about the ordering,
and neither do the manual for older versions (I've checked only a few of
them).

So, this is a change in behaviour, and should be reported upstream as a
bug. Will you do so?
