From e94b4f23277f7572aacbbeae50b8927e03be148a Mon Sep 17 00:00:00 2001
From: Petr Vorel <pvorel@suse.cz>
Date: Thu, 15 Jul 2021 17:35:27 +0200
Subject: [PATCH 1/2] osdep: Introduce include/grub/osdep/major.h and use it
... to factor out fix for glibc 2.25 introduced in 7a5b301e3 (build: Use
AC_HEADER_MAJOR to find device macros).
Note: Once glibc 2.25 is old enough and this fix is not needed also
AC_HEADER_MAJOR in configure.ac should be removed.
