[linux-nfc] [neard][PATCH 2/8] build: replace deprecated AC_HELP_STRING

AC_HELP_STRING is deprecated in favor of AS_HELP_STRING at least since
autoconf v2.60.  In autoconf v2.71 (used on current ArchLinux and Fedora
Rawhide) this causes error:

  configure.ac:112: warning: The macro `AC_HELP_STRING' is obsolete.
  configure.ac:112: You should run autoupdate.
