gnulib-tool: make it easier to distribute library built from gnulib

[Bruno Haible]

This patch makes it easier to distribute a library that was built by
Makefile rules generated by Makefile.am. Previously you had to write

lib_LTLIBRARIES = libgnurepacked.la
libgnurepacked_la_LIBADD = libgnu.la

Now you can write directly

lib_LTLIBRARIES = libgnu.la

        * gnulib-tool (func_emit_lib_Makefile_am): Don't add the library to
        noinst_LTLIBRARIES if the Makefile.am in the same directory specifies
        that it should be installed.
