Is this a known (and filed) bug?  A quick search for defsubst in debbugs only 
finds me one unrelated report.

In any case, doing “make bootstrap” from clean trees (which I’m assuming will 
byte-compile files in the same order each time) still gets me a few differences 
between the branch point and the branch, including python.elc differing in use 
of dynamic docstrings, and url-handler.elc file-name-handler wrappers saying 
“no original documentation”.  Still more to debug, I guess.
