The build test script for bpftool attempts to detect the toplevel path of the kernel repository and attempts to build bpftool from there. If it fails to find the correct directory, or if bpftool files are missing for another reason (e.g. kselftests built on a first machine and copied onto another, without bpftool sources), then it is preferable to skip the tests entirely rather than dumping useless error messages. The first patch moves the EXIT trap in the script lower down in the code, to avoid tampering with return value on early exits at the beginning of the script; then the second patch makes sure that we skip the build tests if bpftool's Makefile is not found at its expected location.
