Dmitry V. Levin 50608a4098 Do not use AC_HEADER_MAJOR, include <sys/sysmacros.h> unconditionally
glibc, starting with commit glibc-2.24-28-gdbab657, has deprecated
inclusion of <sys/sysmacros.h> by <sys/types.h>.  The method used
for deprecation breaks AC_HEADER_MAJOR: this autoconf macro no longer
defines MAJOR_IN_SYSMACROS, which consequently breaks build.

Let's assume that all systems supported by strace provide major, minor,
and makedev macros via <sys/sysmacros.h>.

* configure.ac (AC_HEADER_MAJOR): Remove.
* mknod.c [MAJOR_IN_SYSMACROS, MAJOR_IN_MKDEV]: Remove.
Include <sys/sysmacros.h> unconditionally.
* print_struct_stat.c: Likewise.
* tests/mknod.c: Likewise.
* tests/mknodat.c: Likewise.
* tests/xstatx.c: Likewise.
