Hi,

GNU Make now has a --shuffle option that simulates non-deterministic ordering
of target prerequisites. See
https://trofi.github.io/posts/238-new-make-shuffle-mode.html and also previous
work in Debian by Santiago Vila:
https://people.debian.org/~sanvila/make-shuffle/

This package fails to build with make --shuffle=reverse.
This is likely to be caused by a missing dependency in
debian/rules or an upstream Makefile.

More information about this mass bug filing is available at
https://wiki.debian.org/qa.debian.org/FTBFS/Shuffle
