Log:
    cmd/go: pass -funwind-tables when compiling C code
    
    Using -funwind-tables is necessary to permit Go code to correctly
    throw a panic through C code.  This hasn't been necessary in the past
    as -funwind-tables is the default on x86.  However, it is not the
    default for PPC AIX.
