bug#19514: 25.0.50; byte-compile-file too tight-lipped

[Katsumi Yamaoka]

Hi,

The byte compiler is now too quiet if it runs in the batch mode.
For instance, this is what I got when compiling Ma Gnus:

[...]
lispdir="/usr/local/share/emacs/25.0.50/site-lisp/gnus" srcdir=. emacs-25.0.50 
-batch -q -no-site-file -l /usr/local/share/emacs/site-lisp/no-site-lisp.el -l 
./dgnushack.el -f dgnushack-compile
No MH variant found on the system

I cannot see what Lisp modules are blamed.  This seems to be due
to the recent change <cd2d58c1c81d608d6e1aefe1eb8a3d1f1cd60540>.

Thanks.
