    binutils/readelf: Remove unused static variables
    
    Remove static variables do_ctf and do_sframe that are set but never
    read, causing build failures with LLVM's extended
    -Wunused-but-set-variable warning.
    
    These variables are dead code:
    - Declared at lines 244-245 as static booleans
    - Set to true when --ctf or --sframe options are parsed
    - Never actually used or read anywhere in the code
    - The actual dump functionality is triggered by request_dump() calls
    
    Build error with -Werror enabled:
    
    binutils/readelf.c:244:13: error: variable 'do_ctf' set but not used
      [-Werror,-Wunused-but-set-variable]
    binutils/readelf.c:245:13: error: variable 'do_sframe' set but not used
      [-Werror,-Wunused-but-set-variable]
