oh, I missed the setting in Makefile, I was looking in the cmake files
in the distribution :)

Then, I think the combination of the two diffs would probably be best,
which will build with symbols on archs which provide debug packages,
and without symbols otherwise.

This is essentially the same as produced by my earlier diff, with a
debug-prusaslicer package that has the difference. 

$ ls -lh fake-amd64/usr/local/bin/{,.debug}
fake-amd64/usr/local/bin/:

ok?
