configure: Replace obsoleted AC_HELP_STRING with AS_HELP_STRING

This patch replaces obsoleted AC_HELP_STRING with AS_HELP_STRING.
As of Glibc 2.33, INSTALL says "GNU 'autoconf' 2.69 (exactly)" is
required. So we can safely replace obsoleted macro without worrying
about older autoconf.
This change doesn't affect the contents of "configure" file.
