[Buildroot] [git commit] boot/syslinux: fix build with glibc 2.28+

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=c91e7da5cf6ecf4690148751f72a4185da6243a0
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

When building with glibc 2.28+, the "major", "minor" and "makedev"
functions are defined in "sys/sysmacros.h". This commit backports
upstream commit 1a74985b2a404639b08882c57f3147229605dfd5 to fix the
build with glibc 2.28.

+Subject: [PATCH] extlinux: pull in sys/sysmacros.h for major/minor/makedev
+
+These functions are defined in sys/sysmacros.h, so add the include to
+main.c.  This is already handled correctly in mountinfo.c.  Otherwise
+we get build failures like:
+
+main.o: In function 'find_device_sysfs':
+extlinux/main.c:1131: undefined reference to 'minor'
