Comment:
1. Ol tested and works for years without additional impact of "_FORTIFY_SOURCE",
1. "_FORTIFY_SOURCE" checks for Ol is mainly useless due to:
   1. no `printf` usage,
   2. no system memory allocations - Ol has it's own heap with GC (only one `malloc` and `realloc`s if necessary)
   3. no `memmove`, `bcopy`, etc.
1. Annoying multiple warnings `#  warning _FORTIFY_SOURCE requires compiling with optimization (-O)` in `make check` (that makes checks for 32- and 64-, debug, release, mingw targets).

In fact, a separate test cycle for "__USE_FORTIFY_LEVEL" is planned. But at the moment no such a test target is prepared.
