commit 4c13992f5dc587883ae123df4b352859c44c9feb
Author: Jocelyn Turcotte <jturcotte at woboq.com>
Date:   Fri Mar 6 19:06:38 2015 +0100

    Add a gen_sym_files script for OSX
    
    This attempts to replicate what i686-w64-mingw32-gen_sym_files
    is doing for us with MinGW by parsing the output of otool -L
    to get the library name actually used by the executable.
