Yeah, that is pretty sucky.  What about installing the modules to a bogus 
directory (in the build tree?) and then removing that directory?

    if !INSTALL_LIBS
    pkglibdir = $(top_builddir)/_noinst
    install-exec-hook:
            @echo "pruning statically linked modules"
            rm -rf $(pkglibdir)
    endif

Or, if you give the modules their own Makefile.am, you might be able to 
redefine INSTALL and mkinstalldirs to neuter the install rules:

    if !INSTALL_LIBS
    INSTALL=:
    mkinstalldirs=:
    endif

Cheers,
        Gary.
