Ubuntu mainline builds for ppc64le are failing with the below error (*):

resolve_btfids needs to be build as a host binary and it needs libbpf.
However, libbpf Makefile hardcodes an include path utilizing $(ARCH).
This results in mixing of cross-architecture headers resulting in a
build failure.
The specific header include path doesn't seem necessary for a libbpf
build. Hence, remove the same.
