-+
-+Clang warns on 32-bit ARM on this comparision
-+
-+libbpf.c:10497:18: error: result of comparison of constant 4294967296 with expression of type 'size_t' (aka 'unsigned int') is always false [-Werror,-Wtautological-constant-out-of-range-compare]
-+        if (ref_ctr_off >= (1ULL << PERF_UPROBE_REF_CTR_OFFSET_BITS))
-+            ~~~~~~~~~~~ ^  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-+
-+Check for platform long int to be larger than 32-bits before enabling
-+this check, it false on 32bit anyways.

-+Subject: [PATCH 2/2] perf python: Account for multiple words in CC
-+
-+Sometimes build systems may append options e.g. --sysroot etc. to CC
-+variable especially in cross-compile environments like yocto project
-+where CC varable is composed of cross-compiler name and some needed
-+options for it to work in a relocatable environment. Therefore separate
-+out the compiler name from rest of the options in CC, then add the
-+options via second argument to Popen() API
