perf build: Autodetect minimum required llvm-dev version
The new LLVM addr2line feature requires a minimum version of 13 to compile. Add a feature check for the version so that NO_LLVM=1 doesn't need to be explicitly added. Leave the existing llvm feature check intact because it's used by tools other than Perf. This fixes the following compilation error when the llvm-dev version doesn't match: util/llvm-c-helpers.cpp: In function 'char* llvm_name_for_code(dso*, const char*, u64)': util/llvm-c-helpers.cpp:178:21: error: 'std::remove_reference_t<llvm::DILineInfo>' {aka 'struct llvm::DILineInfo'} has no member named 'StartAddress' 178 | addr, res_or_err->StartAddress ? *res_or_err->StartAddress : 0); Fixes: c3f8644c21df9b7d ("perf report: Support LLVM for addr2line()") Signed-off-by: James Clark <james.clark@linaro.org> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Bill Wendling <morbo@google.com> Cc: Changbin Du <changbin.du@huawei.com> Cc: Guilherme Amadio <amadio@gentoo.org> Cc: Ian Rogers <irogers@google.com> Cc: Ingo Molnar <mingo@redhat.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Justin Stitt <justinstitt@google.com> Cc: Kan Liang <kan.liang@linux.intel.com> Cc: Leo Yan <leo.yan@arm.com> Cc: Manu Bretelle <chantr4@gmail.com> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Masami Hiramatsu <mhiramat@kernel.org> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Nathan Chancellor <nathan@kernel.org> Cc: Nick Desaulniers <ndesaulniers@google.com> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Quentin Monnet <qmo@kernel.org> Cc: Steinar H.
