ARM platform is not supported properly

Currently the targettriple is always set to x86 in the src/cc/bpf_module.c even when it is built on ARM platform.
int BPFModule::finalize() {
Module *mod = &*mod_;

mod->setDataLayout("e-m:e-p:64:64-i64:64-n32:64-S128");
mod->setTargetTriple("bpf-pc-linux");
......
}
So please add ARM platform support.

Start in src/cc/bpf_module.c at BPFModule::finalize(), where the data layout and target triple are set. Compare the current configuration with the ARM build context; the issue is complete when ARM builds use appropriate target settings without regressing x86 behavior.
