autoconf: modernize AC_C_VARARRAYS for C11

* lib/autoconf/c.m4 (AC_C_VARARRAYS): Define __STDC_NO_VLA__ if
VLAs are not supported, as this is what C11 does.  The old macro
HAVE_C_VARARRAYS is still defined if they are supported, but is
now obsolescent.  Also, check for VLA bug in GCC 3.4.3.
* doc/autoconf.texi (C Compiler), NEWS: Document the above.
