Subject: bpf: unbreak libelf linkage for bpf obj loader
Patch-mainline: v4.13.0
Git-commit: 8cc360fe483d028ec39ec2b74ba18a7b95f4520e
References: bsc#1085669

Commit 69fed534a533 ("change how Config is used in Makefile's") moved
HAVE_MNL specific CFLAGS/LDLIBS for building with libmnl out of the
top level Makefile into sub-Makefiles. However, it also removed the
HAVE_ELF specific CFLAGS/LDLIBS entirely, which breaks the BPF object
loader for tc and ip with "No ELF library support compiled in." despite
having libelf detected in configure script. Fix it similarly as in
69fed534a533 for HAVE_ELF.
