llvm 5.0 does not like the section name and the function name
to be the same:
clang -I. -I./include/uapi -I../../../include/uapi \
-I../../../../samples/bpf/ \
-Wno-compare-distinct-pointer-types \
-O2 -target bpf -c \
linux/tools/testing/selftests/bpf/test_obj_id.c -o \
linux/tools/testing/selftests/bpf/test_obj_id.o
fatal error: error in backend: 'test_prog_id' label emitted multiple times to
assembly file
clang-5.0: error: clang frontend command failed with exit code 70 (use -v to
see invocation)
clang version 5.0.0 (trunk 304326) (llvm/trunk 304329)
This patch makes changes to the section name and the function name.
Fixes: 95b9afd398 ("bpf: Test for bpf ID")
