As far as I can tell the other sources files are not necessarily
in `..'.  For instance during a VPATH-build we'd have to search
them in `../$srcdir' (in case `$srcdir' is a relative path) or
in `$srcdir' (if it's absolute).  Elisp files could also comes
from subdirectories.

I see this issue was already reported in 2000, without answers.
http://sources.redhat.com/ml/automake/2000-05/msg00016.html

Wouldn't it be better to teach Automake to byte-compile all
files at once rather than one at a time?  I'm willing to do this
if people agree.  My impression is that the reason why Automake
byte-compile files one at a time is that it's easier to write
Makefile rules this way.  (Make's semantics make it tricky to
write rules with multiple outputs.)
