bug#33049: 27.0.50; Uncompiled .el files after make -- intentional?

[Live System User]

Hi,

        Recently, I noticed after a git pull and make, some
        files are now not being byte-compiled

-rw-rw-r--.  1 liveuser liveuser 181985 Oct 13 22:54 tramp.el
-rw-rw-r--.  1 liveuser liveuser 217141 Oct  9 14:55  tramp.elc

-rwxrwxr-x. 3 liveuser liveuser 18233704 Oct 14 23:57 src/emacs


       The only commonality I can discern is that .el files prior to
       that date and time (Oct 13 22:54) are byte-compiled.

       Here's the message I saw after doing a `make', starting
       a new Emacs sessiom and C-x C-f /ssh:/localhost:/test.txt

Source file ‘/tmp/emacs-27.0-git-master/lisp/net/tramp.el’ newer than 
byte-compiled file

       So what triggers a byte-compilation when doing a `make'?

       What caused tramp.el to not be recompiled after a
       subsequent `make'?

       (I normally do a `make TAGS' if that matters, FWIW).
       
       Thanks.
