Subject: [PATCH] Revert "core: add extra compiler options to check overflow of
 destination buffer and output truncation"

This reverts commit 4ff4a64209f63cf2a048f7941168336da58727ab.

These compiler flags are not supported on old compiler version, for example on
Debian Stretch/Jessie and Ubuntu Xenial (16.04).
