[LTP] [PATCH] statx: fix compile errors with glibc<2.28

[Cyril Hrubis]

Hi!

What's wrong with the configure checks we do have?

See m4/ltp-statx.m4:

AC_CHECK_TYPES([struct statx],,,[[#include <sys/stat.h>]])
AC_CHECK_TYPES([struct statx_timestamp],,,[[#include <sys/stat.h>]])

That should check exactly if these structures are defined and export the
HAVE_STRUCT_* macros?
