[xml/sgml-pkgs] Bug#1105428: libxml2: FTBFS with make --shuffle=reverse: configure: error: source directory already configured; run "make distclean" there first

Source: libxml2
Version: 2.12.7+dfsg+really2.9.14-0.4
Severity: minor

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

Relevant part (hopefully):
> checking for gawk... no
> checking for mawk... mawk
> checking whether make sets $(MAKE)... yes
> checking whether make supports nested variables... yes
> checking xargs -n works... yes
> configure: error: source directory already configured; run "make distclean" there first
> 	cd builddir/python3.13 && tail -v -n \+0 config.log
