1,global variable declaration will compile to .rodata/.bss section in ELF file.
2, haveMapMutabilityModifiers variable will create
ARRAYtype ebpf map withBPF_F_RDONLY_PROGflag to detect system supported in syscalls.go .3. so need to remove global variable on kernel version less than 5.2 via haveMapMutabilityModifiers in cilium/ebpf/syscalls.go
4. more info cilium/ebpf@f5942f5
