    include symbols needed by GNU BFD ld in map
    
    On FreeBSD using the default GNU BFD linker, the use of --version-script
    fails unless the symbols `__progname` and `environ` are included. This
    change includes them in the symbol map, which should allow the build to
    succeed on FreeBSD.
