[PATCH 0/2] xfsprogs: Fix compiling against musl libc

[Johannes Nixdorf <johannes@nixdorf.dev>]

The musl libc statx interface is provided independently from the
kernel headers, so not all defines from the kernel header (here:
STATX__RESERVED) are exported, and checking linux/stat.h as in the
current configure test checking for newest additions to struct statx
will not provide a result that is consistent with the actual code
using the libc interface.

On Alpine Linux this is already fixed by providing the defines
OVERRIDE_SYSTEM_STATX and STATX__RESERVED manually instead of fixing
up the autodetection (OVERRIDE_SYSTEM_STATX) and providing a fallback
(STATX__RESERVED) [1].
