    stand: Export _start on arm like other architectures
    
    By not exporting _start, we get various warnings of the form:
    
      ld: warning: cannot find entry symbol _start
    
    Note that in practice these don't matter because we manually construct
    our PE header and use objcopy -O binary, so the entry point is set to
    whatever we put explicitly in the PE header, but we should still do the
    right thing and silence these warnings.
    
    This was found in CheriBSD, where bsd.prog.mk has similar logic to
    bsd.lib.mk and sets -Wl,--(no-)fatal-warnings based on LD_FATAL_WARNINGS
    (unlike FreeBSD which only does so in the latter).
