From e7ad28e6fdbffa2b9b1bd376431fb81a5403bcfd Mon Sep 17 00:00:00 2001 From: Ilya Leoshkevich Date: Tue, 2 Jun 2020 19:56:49 +0200 Subject: [PATCH] selftests/bpf: Add a default $(CXX) value When using make kselftest TARGETS=bpf, tools/bpf is built with MAKEFLAGS=rR, which causes $(CXX) to be undefined, which in turn causes the build to fail with CXX test_cpp /bin/sh: 2: g: not found Fix by adding a default $(CXX) value, like tools/build/feature/Makefile already does.
