Hmm, since nobody has replied to my question, I presume there was not enough 
detail in the text. Hence, let me try to be a bit more verbose. ;)
Here is the failing portion of the log:

make install DESTDIR=/home/abuild/rpmbuild/BUILDROOT/samba-4.10.6-

Hence, it seems to be about some dependency cycle in the xml generation inside 
docs-xml. I checked buildtools/wafsamba/samba_waf18.py, but could not find 
anything related to xml.
Any ideas? Thanks a lot in advance!
