I didn't know how to link AC_HEADER_MAJOR with include/grub/osdep/major.h.
Because in the future when glibc 2.25 is old enough the header will be removed
and AC_HEADER_MAJOR might be left in configure.ac (name is different from
MAJOR_IN_{MKDEV,SYSMACROS}). But I can note this in commit message instead.

Kind regards,
Petr
