Add a config macro to qemu to tell it that s390x is intended to populate the `*_nsec` fields in an `fstat` call.

Subject: [PATCH] Define `TARGET_STAT_HAVE_NSEC` for s390x
|
|
|
|
Without this, The `fstat` syscall sets `st_mtime_nsec` and the other `_nsec`
|
|
fields to 0. Libc `fstat` will sometimes use the `fstatat` or `fstat64`
|
|
syscalls instead, which aren't affected, but the libc `fstat` on ubuntu-20.04
|
|
on Github Actions appears to be affected.
|
|
|
|
This can be seen in the `st_mtime_nsec` assert in tests/fs/futimens.rs.
|
|
|
|
It's not yet known why upstream qemu doesn't define this.
