Update from gnulib

This incorporates:
2016-10-16 qsort_r: Fix macrology for platforms that lack the function.
2016-10-13 stdint: port SIZE_MAX to glibc s390
2016-10-11 maint: remove stray space after "." in AC_DEFINE comment.
* lib/gnulib.mk: Regenerate.
* lib/stdlib.in.h, m4/st_dm_mode.m4, m4/stdint.m4, m4/stdlib_h.m4:
* m4/utimes.m4: Copy from gnulib.
