First, AFAIU the relevant Makefile target gets executed in non-Android
builds as well.

And second, if the Android build requires GNU Make >= 4.3, I think
this should be mentioned in java/INSTALL as a prerequisite, even if
the various other Android tools already require or provide such a new
version.

If Mattias says this solves the problem, please install this change.
