Ondřej Surý f52872c3ed Update the configure.ac for autoconf >= 2.71 compatibility
This mostly removes stuff that's either deprecated, obsolete or not used
at all:

* Update the minimal autoconf version to 2.69
* AC_PROG_CC_C99 is deprecated, just use AC_PROG_CC as we require C11
  anyway
* AC_HEADER_TIME is deprecated, both <sys/time.h> and <time.h> can be
  included at the same time, and we don't use the macros that
  AC_HEADER_TIME defines anywhere
* AC_HEADER_STDC checks for ISO C90 and we require at least C11
* Replace AC_TRY_*([]) with AC_*_IFELSE([AC_LANG_PROGRAM()])
* Update m4/ax_check_openssl.m4 from serial 10 to serial 11
* Update m4/ax_gcc_func_attribute.m4 from serial 10 to serial 13
* Update m4/ax_pthread.m4 from serial 24 to serial 30
* Add early AC_CANONICAL_TARGET call to prevent warning from AX_PTHREAD
