I don't see why.  Your problems are all related to outdated Lisp
files, so out-of-tree builds are unlikely to be a factor.  (Which
means I again don't understand why you report a perceptible
degradation in build success rates, while I don't see anything close
to that.)

These are all related to outdated *.elc files.

You mean, when configure is run automatically by "make"?
