Mikhail Gavrilov 3dedeeecd1 libbpf: Fix -Wdiscarded-qualifiers under C23 
commit d70f79fef6 upstream.

glibc ≥ 2.42 (GCC 15) defaults to -std=gnu23, which promotes
-Wdiscarded-qualifiers to an error.

In C23, strstr() and strchr() return "const char *".

Change variable types to const char * where the pointers are never
modified (res, sym_sfx, next_path).

[ shung-hsi.yu: needed to fix kernel build failure due to libbpf since glibc
  2.43+ (which adds 'const' qualifier to strstr). 'sym_sfx' hunk dropped because
  commit f8a05692de ("libbpf: Work around kernel inconsistently stripping
  '.llvm.' suffix") is not present. ]
