This fixes <https://debbugs.gnu.org/41264>. * include/linux/arm/syscall.h (SYS_stat64, SYS_lstat64, SYS_fstat64)[__SIZEOF_LONG_LONG__ == 8]: New defines. (SYS_stat, SYS_lstat, SYS_fstat)[__SIZEOF_LONG_LONG__ == 8]: Redefine them. * include/linux/x86/syscall.h (SYS_stat64, SYS_lstat64, SYS_fstat64)[__SIZEOF_LONG_LONG__ == 8]: New defines. (SYS_stat, SYS_lstat, SYS_fstat)[__SIZEOF_LONG_LONG__ == 8]: Redefine them. * include/sys/stat.h (struct stat): Move definition to... * include/linux/arm/kernel-stat.h, include/linux/m2/kernel-stat.h, include/linux/x86/kernel-stat.h, include/linux/x86_64/kernel-stat.h: These new files. * include/gnu/x86/kernel-stat.h: New file. * configure (main): Copy <srcdest>include/<kernel>/<arch>/*.h to include/. * configure.sh: Likewise. * .gitignore: Ignore them. Add copyright header. * build-aux/GNUmakefile.in (X86_ARCH_HEADERS, ARCH_HEADERS): New variables. (build): Use them. (include/arch/%.h, arch-dir): New targets. * build-aux/bootstrap.sh.in (AM_CPPFLAGS): Replace <srcdest>include/<kernel>/<cpu> with built ../include. * build-aux/build.sh.in (AM_CPPFLAGS): Likewise. * build-aux/install.sh.in: Also install built include. * include/m2/types.h: New file. * kaem.run: Use it. * simple.sh: Copy kernel-stat.h, syscall.h for kernel/cpu to include/arch.
