[OE-core] Run experience with security flags enabled

[Andreas Müller]

Hi,

from oe-core perspective my images are build on sumo (glibc 2.27). To
see what to expect, I enabled security flags (and yes some recipes in
my layers needed rework).

Now that I have an image, I thought: let's give it a run. Apart of
other issues (maybe later) I get on every startup an error message for
ldconfig.
systemctl ldconfig says:

● ldconfig.service - Rebuild Dynamic Linker Cache
   Loaded: loaded (/lib/systemd/system/ldconfig.service; static;
vendor preset: enabled)
   Active: failed (Result: core-dump) since Mon 2018-09-24 19:05:04

     Docs: man:ldconfig(8)
  Process: 136 ExecStart=/sbin/ldconfig -X (code=dumped, signal=SEGV)
 Main PID: 136 (code=dumped, signal=SEGV)

Again somebody else seeing similar / remembers a fix?

Help appreciated
