add missing STATX_ATTR_* constants on gnu/linux

[SteveLauC]

Corresponds to this:

#define STATX_ATTR_MOUNT_ROOT		0x00002000 /* Root of a mount */
#define STATX_ATTR_VERITY		0x00100000 /* [I] Verity protected file */
#define STATX_ATTR_DAX			0x00200000 /* File is currently in DAX state */

Could you add them to https://github.com/rust-lang/libc/blob/master/libc-test/semver/linux-gnu.txt?

[SteveLauC]

Sure thing! Done

Honestly and sadly, I have no idea why these constants are not found on it

[JohnTitor]

Because SPARC64 image on CI is old and doesn't know them:

libc/ci/docker/sparc64-unknown-linux-gnu/Dockerfile

Lines 1 to 2 in a0ff4d2

	# FIXME: Update to 22.04 once Debian image of sparc64 has a newer glibc.
	FROM ubuntu:20.04

You could ignore them on SPARC64 for now.

Thanks for showing me this. Then let's wait for a glibc update on sparc64.

[JohnTitor]

I don't think we have to wait as it's just our CI issue. And these should be the same as on other archs, right? Then ignoring test for SPARC64 won't make a major issue here.

[SteveLauC]

Yes. I am sorry that I misunderstand you at first. Added them to build.rs
