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

Subject: libbpf: Fix build warning on ref_ctr_off
Date: Sun, 4 Dec 2022 18:23:47 -0800
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: tools: Remove some options from CLANG_CROSS_FLAGS
Date: Sun, 4 Dec 2022 18:33:48 -0800
These options are not needed with OE/Yocto since compiler is already
passing these options via TOOLCHAIN_OPTIONS, having these options infact
regressed OE builds because build time --sysroot on OE cross compiler is
/not/exist and that creates problems where clang can no more find system
headers anymore during compilation
