I am afraid it does not answer my question. Yes, .c generated from
.vala are disributed, but why automake deliberately emits code that
cannot built .c files from .vala in *source* directory?

The following crude change to final Makefile builds files in (srcdir)
when started from build directory:

$(srcdir)/src/systemadm.c: $(srcdir)/systemadm_vala.stamp
        @if test -f $@; then :; else \
          rm -f $(srcdir)/systemadm_vala.stamp; \
          $(am__cd) $(srcdir) && $(MAKE) $(AM_MAKEFLAGS)
$(srcdir)/systemadm_vala.stamp; \
$(srcdir)/src/systemd-interfaces.c: $(srcdir)/systemadm_vala.stamp
        @if test -f $@; then :; else \
          rm -f $(srcdir)/systemadm_vala.stamp; \
          $(am__cd) $(srcdir) && $(MAKE) $(AM_MAKEFLAGS)
$(srcdir)/systemadm_vala.stamp; \
$(srcdir)/systemadm_vala.stamp: $(systemadm_SOURCES)
        $(am__cd) $(srcdir) && \
        $(AM_V_VALAC)$(VALAC) $(systemadm_VALAFLAGS) $(VALAFLAGS) -C
        $(AM_V_at)touch $@

Do you see any immediate problem with this change? Could automake
generate similar code by default?

While this is nice wishlist, it is rather orthogonal to discussed problem :)

Thank you!
