I have almost the same tree as yours. My solution is:
Ex:
bin_PROGRAMS = name
name_SOURCES = ...
name_DEPENDENCIES = $(top_builddir)/path/libnoinst.a ...
name_LDADD = $(name_DEPENDENCIES)
The main trick is to explain to make how to rebuild noinst library in other
than current directory.To do this I use the following in my
admin/Makefile.deps (which is included in _EVERY_ Makefile.am's):
#
# Get all depended targets for all 'main' targets as space separated list
#
AM_DEPTGTS := $(sort $(foreach t, \
$(bin_PROGRAMS) $(pkgbin_PROGRAMS) $(lib_LTLIBRARIES)
$(pkglib_LTLIBRARIES) \
$(noinst_LIBRARIES) $(LIBRARIES) $(check_PROGRAMS), \
$($(addsuffix _DEPENDENCIES, $(subst .,_,$(subst
-,_,$(t)))))))
#
# Rule to make all depended libs
#
$(AM_DEPTGTS):
+@$(MKMSG) "Make depended target \`$(@)'"; \
$(MAKE) $(AM_MAKEFLAGS) -C $(@D) $(DEPDIR)/includes && \
$(MAKE) $(AM_MAKEFLAGS) -C $(@D) $(@F) || exit 1
... so make will know how to build $(top_builddir)/path/libnoinst.a (and other
depended libs)
good luck
