[OE-core] [oe-core][RFC] zlib: export LDCONFIG = true to disable runnig host's ldconfig

[Martin Jansa]

* it's called from install-libs target and when /etc/ld.so.cache is writeable by user running bitbake
  then it creates invalid cache (in my case libstdc++.so cannot be found after building zlib(-native)
  and I have to call touch */libstdc++.so && /sbin/ldconfig to fix it
