In fact, I had a line in Makefile.am like that but with the full path 
libcontrol_la_DEPENDENCIES =
$(top_builddir)/routines/foo/libdummy-foo.la
which is the right path.
I guess the problem I had was caused by the fact that automake does not
understand that $(top_builddir)/routines/foo/libdummy-foo.la ==
libdummy-foo.la

Thank you (again)
