See `info Autoconf FAQ defining' for general instructions.
A correction, though:
I'd use
  AM_CPPFLAGS = -DDATADIR='"$(datadir)"'
instead of modifying CPPFLAGS.

I think it is OK to use the default value of sysconfdir and let the
user configure with --sysconfdir=/etc if that is what they want.
(GNU/Linux distributions often set that in their build scripts.)

It is possible to do some hacks in so that the default
is /etc.  (And you can then use DISTCHECK_CONFIGURE_FLAGS to revert
that change for distcheck, so that it passes.)

I guess that in that case it might be best to foget about
sysconf_DATA, and use install-exec-local for the installation of
the config file.  (You would use EXTRA_DIST to distribute your
default config file, of course.)
