iproute2: fix libbpf detection with NLS enabled

Upstream iproute2 detects libbpf using a one-line $CC test-compile, which
normally ignores LDFLAGS. With NLS enabled however, LDFLAGS includes an
"rpath-link" linker option needed to resolve libintl.so. Its absence
causes both the compile and libbpf detection to fail:

  ld: warning: libintl.so.8, needed by libbpf.so, not found (try using
      -rpath or -rpath-link)
  ld: libelf.so.1: undefined reference to `libintl_dgettext'
  collect2: error: ld returned 1 exit status

Fix this by directly including $LDFLAGS in the test-compile command.
