This pulls in support for the latest kernel features. Additionally,
it includes the following spec file changes:
- get rid of the leading slash in front of the libdir macros
- pass --use-libc so that -fstack-protector will work
- add new library variants for foreign function interfaces (ffi).
This allows other languages to link against and call functions
in liburing.
