If you are building a library that is not installed you can use libtool
as follows:

noinst_LTLIBRARIES = libfakelib.la

You now need to tell automake whare the source files for it.

libfakelib_la_SOURCES = bin_a.c bin_bf.c

If you don't want to install the headers you do as you did above.

noinst_HEADERS = bin_a.h bin_b.h

Now if you have a binary program you do:

bin_PROGRAMS = reallyfake

reallyfake_SOURCES = soo.c foo.c rah.c
reallyfake_LDADD = -lfakelib

There is no need to distinguish between the bin and the library. In the
example above we have a library which is only used to compile reallyfake
but its not installed. We are not interested in installing the headers
so we used the 'noinst' prefix for HEADERS.

Now what if we want to allow people to use your libfakelib for creating
a application that uses it. We have to give them the C header to compile
against as well as the library. Yet we don't want to install all the
headers. Here is the example

# Notice we are not preventing the library from being installed
lib_LTLIBRARIES =  = libfakelib.la

# Same sources as before
libfakelib_la_SOURCES = bin_a.c bin_bf.c

# We don't install bin_a.h
noinst_HEADERS = bin_a.h

# We do install the bin_b.h to $(prefix)/include/fakelib
library_includedir=$(includedir)/fakelib
library_include_HEADERS = bin_b.h

# Same binary program
bin_PROGRAMS = reallyfake

# Same binary sources
reallyfake_SOURCES = soo.c foo.c rah.c
reallyfake_LDADD = -lfakelib
