Then what you typically do is create a convenience library in each of
the sub directories, and at the end merge them together.

--- sub/Makefile.am ---
noinst_LTLIBRARIES = libconv.la
libconv_la_SOURCES = ...

--- Makefile.am ---
lib_LTLIBRARIES = libmylib.la
libmylib_la_SOURCES =
## yes, the previous line can be empty
libmylib_la_LIBADD = sub/libconv.la sub2/libconv.la ...

Get rid of that -c.

Hope that helps.

Alternatively, you can look into nonrecursive make setups, and do
something like

--- Makefile.am ---
lib_LTLIBRARIES = libmylib.la
libmylib_la_SOURCES = sub/file1.c sub2/file3.c ...

Cheers,
