commit 57711cc2167f4fc4dc5a03f1b7e3b43e5c7e8050
Author: Raymond Toy <toy.raymond at gmail.com>
Date:   Wed Oct 8 17:44:04 2014 -0700

    First cut at removing ppc-darwin-dlshim.c. Not needed anymore because
    dlsym works on OSX/ppc like on other ports.
    
    A cross-compile was used with cross-ppc-ppc-darwin.lisp.  I'm not sure
    a cross-compile is required, though.
    
     * code/ppc-vm.lisp:
       * EXTERN-ALIEN-NAME doesn't need to prepend an underscore anymore.
     * lisp/Config.ppc_darwin:
       * Don't compile/link ppc-darwin-dlshim.c.
     * lisp/os-common.c:
       * Don't prepend underscore for call_into_lisp.
     * tools/cross-scripts/cross-ppc-ppc-darwin.lisp:
       * EXTERN-ALIEN-NAME doesn't need to prepend an underscore anymore.
