Regarding the syscall ABI change taking out fstat and newfstatat, I've
done the following to ensure a clean path forward:

- Sent glibc patch [1] for upstream review;
- Filed [2] on Loongson's glibc fork for them to test, and incorporate
the 2nd patch in their port;
- Updated my tool [3] for the small number of end users already on the
previous ABI (me included, actually), to easily check if their systems
are compatible before moving to newer kernels.
