[PATCH] binutils/readelf: Remove unused static variables

[Bratislav Filipovic]

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]
