Thanks.

Andrea, this means bug#48978 was not entirely fixed: we are still
trying to write the *.elc files when native-compiling.  Your last
change prevented Emacs from trying to create a temporary file under
/usr/share/emacs, but it didn't prevent the rest of byte-compile-file
from trying to overwrite the original .elc file, which here causes us
to signal an error.  We need to avoid writing the .elc file entirely
in this case, I think.
