bug#45186: Emacs master: build broken by spurious message ".../c-by.elc failed to provide feature `semantic/bovine/c-by"

[Alan Mackenzie]

Hello, Emacs.

I've just updated a master repo here, and tried a make bootstrap.

I get the error message:

    cedet/semantic/bovine/c.el:35:1: Error: Loading file
    /home/acm/emacs/emacs.git/sub-master-a/lisp/cedet/semantic/bovine/c-by.elc
    failed to provide feature `semantic/bovine/c-by'

.  There is a perfectly good line at the end of this file:

    (provide 'c-by)

.  So what is expecting the compound symbol `semantic/bovine/c-by' to be
provided, and why?
