Bug report

Compilation error:
error: ‘int openat2(int, const char*, const open_how*, size_t)’ was declared ‘extern’ and later ‘static’

The test for openat2 at src/system/linux/openat2.h should be for HAVE_OPENAT2 instead of for HAVE_NATIVE_OPENAT2. HAVE_OPENAT2 cover both tests: system_linux_features.set('HAVE_OPENAT2', have_native_openat2 or compiler.has_header('linux/openat2.h')).
