This is unfortuantely not sufficient:

    [...] /usr/bin/make -j1 DESTDIR=/home/ymorin/dev/buildroot/O/target install_device-mapper install_systemd_units install_systemd_generators -C /home/ymorin/dev/buildroot/O/build/lvm2-2.03.12/
    [...]
    /usr/bin/make -C scripts install_systemd_generators
        [INSTALL] systemd_generators
    /usr/bin/install: cannot stat 'lvm2_activation_generator_systemd_red_hat': No such file or directory
    make[3]: *** [Makefile:86: install_systemd_generators] Error 1
    make[2]: *** [Makefile:141: install_systemd_generators] Error 2
    make[1]: *** [package/pkg-generic.mk:341: /home/ymorin/dev/buildroot/O/build/lvm2-2.03.12/.stamp_target_installed] Error 2
    make: *** [Makefile:23: _all] Error 2

This is probably because, in the systemd case, we force the installation
of systemd stuff:

   66 ifeq ($(BR2_INIT_SYSTEMD),y)
   67 LVM2_INSTALL_TARGET_OPTS += install_systemd_units install_systemd_generators
   68 endif

But nothing ensures they are actually built.

I suspect commit cb0ce03ba636 (package/lvm2: install systemd units and
generators) is no longer valid after the bump to 2.03.x

Pascal, you came up with the systemd integration. Could you also have a
look at this build failure, please?
