Sergei Golubchik aa36d9e742 MDEV-5120 Test suite test maria-no-logging fails 
stat structure (from <sys/stat.h>) is conditionally defined
to have different layout and size depending on the defined macros.
The correct macro is defined in my_config.h, which means it MUST be
included first (or, at least before <features.h> - so, practically,
before including any system headers).
