Remove AC_C_VARARRAYS from configure.ac
With autoconf 2.70, the behaviour of AC_C_VARARRAYS has changed,
causing a lot of warnings and as a result a cluttered make output.
Doing some research as to where this comes from, I found an strange
piece of code that seems to rely on a misunderstanding as to VLA's
in C++. As I found, the C++ standard does not have VLA's. The
configure.ac code and some code in libFLAC++ seems to think it does.
This now causes strange behaviour.
This commit removes the code relying on this behaviour and removing
all VLA related autoconf macro's from configure.ac
