Two ways I could think of:
- with a hack (using nonpublished internal Automake details):

  install-libonly: install-libLTLIBRARIES

(if the library is not created with libtool, I guess that would be
install-libLIBRARIES).  This may fail with any future Automake version
(or older, FWIW, tested only with 1.9.6).

- without a hack: by replicating the rule Automake generates:

install-libonly: $(lib_LTLIBRARIES)
        test -z "$(libdir)" || $(mkinstalldirs) "$(DESTDIR)$(libdir)"
        @list='$(lib_LTLIBRARIES)'; for p in $$list; do \
          if test -f $$p; then \
            f=`echo $$p | sed -e 's|^.*/||'`; \
            echo " $(LIBTOOL) --mode=install $(INSTALL) $(INSTALL_STRIP_FLAG) 
'$$p' '$(DESTDIR)$(libdir)/$$f'"; \
            $(LIBTOOL) --mode=install $(INSTALL) $(INSTALL_STRIP_FLAG) "$$p" 
"$(DESTDIR)$(libdir)/$$f"; \
          else :; fi; \

with modifications should your library not be created with libtool or
have a different directory prefix (the `lib' in lib_LTLIBRARIES,
corresponding to `libdir').

Should you use a recursive Makefile structure, you'd need to write the
necessary recursion targets as well, unfortunately.
