[libc-commits] [libc] [libc][annex_k] Add errno_t. (PR #163094)

It seems that `errno_t` should be defined by the following header files:
- errno.h
- stdio.h 
- stdlib.h
- string.h
- time.h

However the patch only adds the type definition to `errno.h`. I don't see the remaining header files either defining it or including `errno.h` to obtain it.
