selftests: bpf: fix urandom_read build issue
gcc complains that urandom_read gets built twice. gcc -o tools/testing/selftests/bpf/urandom_read -static urandom_read.c -Wl,--build-id gcc -Wall -O2 -I../../../include/uapi -I../../../lib -I../../../lib/bpf -I../../../../include/generated -I../../../include urandom_read.c urandom_read -lcap -lelf -lrt -lpthread -o tools/testing/selftests/bpf/urandom_read gcc: fatal error: input file ‘tools/testing/selftests/bpf/urandom_read’ is the same as output file compilation terminated. ../lib.mk:110: recipe for target 'tools/testing/selftests/bpf/urandom_read' failed To fix this issue remove the urandom_read target and so target TEST_CUSTOM_PROGS gets used. Fixes: 81f77fd0deeb ("bpf: add selftest for stackmap with BPF_F_STACK_BUILD_ID") Signed-off-by: Anders Roxell <anders.roxell@linaro.org> Acked-by: Yonghong Song <yhs@fb.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>
