This patch makes __ASSUME_UTIMES hppa-specific, removing mentions of the macro from architecture-independent code and code for other architectures. (All other architectures either have the utimes syscall in all relevant kernel versions, or use the asm-generic interface so only have utimensat and won't get the utimes syscall.) A similar approach is used to that used for futimesat for MicroBlaze: if the kernel is recent enough that the utimes syscall can be assumed to be present, use the implementation in terms of the utimes syscall, and otherwise use the linux/generic implementation in terms of utimensat. Tested x86_64 that the disassembly of installed shared libraries is unchanged by the patch. Not tested for hppa. * sysdeps/unix/sysv/linux/kernel-features.h (__ASSUME_UTIMES): Do not define. * sysdeps/unix/sysv/linux/utimes.c: Do not include <kernel-features.h>. (__utimes) [__NR_utimes]: Make code unconditional. (__utimes) [!__ASSUME_UTIMES]: Remove conditional code. * sysdeps/unix/sysv/linux/aarch64/kernel-features.h (__ASSUME_UTIMES): Do not undefine. * sysdeps/unix/sysv/linux/tile/kernel-features.h (__ASSUME_UTIMES): Likewise. * sysdeps/unix/sysv/linux/hppa/kernel-features.h (__ASSUME_UTIMES): Define for [__LINUX_KERNEL_VERSION >= 0x030e00] instead of undefining for [__LINUX_KERNEL_VERSION < 0x030e00]. * sysdeps/unix/sysv/linux/hppa/utimes.c: New file.
