AC_PROG_CC_C89, AC_PROG_CC_C99, AC_PROG_CC_STDC: Use AU_ALIAS.

Based on a suggestion by Adrian Bunk in
http://lists.gnu.org/archive/html/autoconf-patches/2012-09/msg00040.html
* lib/autoconf/c.m4 (AC_PROG_CC_C89, AC_PROG_CC_C99, AC_PROG_CC_STDC):
Use AU_ALIAS, now that AC_PROG_CC is defined via AC_DEFUN_ONCE.
