Improve out-of-tree builds
Several make rules don't work when building out-of-tree. There are also some files that aren't cleaned up on make clean
or make distclean
. Lastly, some file generation blobs don't work properly by leaving temporary files behind.
These are just some of the things i have ran into so far and i am currently patching these issues.
Also creating this ticket to discuss certain parts of the build configuration that are unfamiliar and for which the reasons of implementation can't be traced back.
