LLC is meant for compiler development and debugging. Consequently, it exposes many low level options about its backend. To avoid future bugs introduced by using the raw LLC tool, use clang directly so that all appropriate options are passed to the back end. Additionally, simplify the Makefile by removing the CLANG_NATIVE_BPF_BUILD_RULE as it is not being use, stop passing dwarfris attr since elfutils/libdw now supports the bpf backend (which should work with any recent pahole), and stop passing alu32 since -mcpu=v3 implies alu32.
