  To: buildroot; +Cc: Norbert Lange

The build still fails with older glibc versions (2.28 for example).
Apply an upstream fix from
https://github.com/util-linux/util-linux/issues/2448.

+Subject: [PATCH] libmount: fix statx() includes
+
+Using sys/stat.h and linux/stat is too tricky.h together. It seems
+better to rely on libc and use sys/stat.h only. Users affected
+by old libc must update to use recent util-linux.
