    libtool: Don't fall back to static libraries if building them was disabled
    
    If -no-undefined was not specified but the platform didn't
    support shared libraries with undefined symbols (e.g. Cygwin/
    MinGW), static libraries were built instead of shared ones,
    even if building them was explicitly disabled with --disable-
    static configure option.
    
    Fix this by stopping with a fatal error if a shared library
    can't be built in this case instead of unexpectedly building a
    static library instead.
    
    * libltdl/config/ltmain.m4sh (func_mode_link()): Stop with
    fatal error when trying to build a shared library without -no-
    undefined on a platform not supporting undefined symbols in
    shared libraries.
