fio checks libaio via test C code embedded in ./configure script when compiling,
rather than whether you have certain RPMs in certain distro or not.
See around L543 of ./configure where it says "linux-aio probe".
It seems your environment failed to compile the test code embedded
here, and $libaio flag has stayed "no".
