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
#
$(AM_DEPTGTS):
        address@hidden(MKMSG) "Make depended target \`$(@)'"; \
        $(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
