make error like:
/usr/bin/ld: ../libbpf/src/libbpf.a(libbpf.o): warning: relocation against `stderr@@GLIBC_2.2.5' in read-only section `.text'
/usr/bin/ld: ../libbpf/src/libbpf.a(libbpf.o): relocation R_X86_64_PC32 against symbol `stderr@@GLIBC_2.2.5' can not be used when making a shared object; recompile with -fPIC

This is not related to the libbpf version. Did you manually build libbpf in the subdirectory before running 'make' in the parent xdp-tools directory? Please try a clean build ('make clobber' followed by 'make') and see if you still get this error.
