    fix spelling of -linker-output-auto-nolto-rel
    
    The transposition nolto -> notlo is confusing and it makes the long
    name even harder to read than it already is - I kept reading it as
    "not lo" until I realized it was a simple typo.
    
    Fixes: 5269b24605b1 (Silence warning in LTO mode on VxWorks)
    
    lto-plugin/
            * lto-plugin.c: Fix -linker-output-auto-notlo-rel ->
            -linker-output-auto-nolto-rel typo.
            (process_option): Adjust accordingly, accepting both old and
            new spelling.
    
    gcc/
            * config/vxworks.h (LTO_PLUGIN_SPEC): Adapt to corrected
            spelling of -linker-output-auto-nolto-rel.
