configure.ac, allow cross-compilation, especially for MinGW-w64

notably on debian gnu/linux with package `mingw-w64'
cross-compile a mingw 32bit windows executable with this incantation:

(compile "
  ./autogen.sh
  rm -rf tmp-build tmp-output
  mkdir -p tmp-build tmp-output
  ( cd tmp-build && ../configure \
      --build=$(../config.guess) \
      --host=i686-w64-mingw32 \
      --prefix='c:/spice' \
      --exec-prefix='c:/spice'\
      --with-windows --enable-xspice --enable-cider --disable-debug )
  LC_ALL=C make -C tmp-build -k -j6
  LC_ALL=C make -C tmp-build -k -j6 DESTDIR=$(pwd)/tmp-output/ install
  (cd 'tmp-output/c:/' && zip -r - .) > tmp-output.zip
")

compilation to Win64 works the same way, with
      --host=x86_64-w64-mingw32

The tmp-output.zip directory structure resembles the
  structure of our original sourceforge ngspice-26_140112.zip windows package
ready to be unzip'ed in c:/

Though the testfiles, examples and documentation is missing.

#
# SYNOPSIS
#
# AX_PROG_CC_FOR_BUILD
#
# DESCRIPTION
#
# This macro searches for a C compiler that generates native executables,
# that is a C compiler that surely is not a cross-compiler. This can be
# useful if you have to generate source code at compile-time like for
# example GCC does.
#
# The macro sets the CC_FOR_BUILD and CPP_FOR_BUILD macros to anything
# needed to compile or link (CC_FOR_BUILD) and preprocess (CPP_FOR_BUILD).
# The value of these variables can be overridden by the user by specifying
# a compiler with an environment variable (like you do for standard CC).
#
# It also sets BUILD_EXEEXT and BUILD_OBJEXT to the executable and object
# file extensions for the build platform, and GCC_FOR_BUILD to `yes' if
# the compiler we found is GCC. All these variables but GCC_FOR_BUILD are
# substituted in the Makefile.
