With this type of setup, ENABLE_SYSTEMD must imply ENABLE_TOOLS and
ENABLE_UDEV.
The first stage of this will be breaking up Makefile.am and using
includes without condissionals. Once everything builds cleanly in that
setup, we can do the work in configure.ac and add condissionals to
Makefile.am.
The first thing that will have to be done is to break up
libsystemd_shared_la_SOURCES in Makefile.am. That definition combines
files incompatible with udev-only with files required by udev. udev needs:
log
label
mkdir
cgroup-util
strv
path-util
conf-files
hashmap
set
exit-status
util
dev-setup
but does not need:
cgroup-show
conf-parser
hwclock
pager
ratelimit
socket-util
spawn-ask-password-agent
spawn-polkit-agent
specifier
utf8
virt
watchdog
Basically all of the above are combined into libsystemd-core.la and that
needs to be split into two. I'd just split the first group into
libudev-core.la.
To link, udev also needs the file in libsystemd_daemon_la_SOURCES
(sd-daumon) for udevd, but that probably could be removed with some
appropriate ifdefs in udevd.c.
