autoconf-2.1.3

So this is a suggestion, not a bug.  There is a lot of software that I
cannot get to cross-compile because the configure script does a test
which requires the compilation and running of some code.  Instead of
expanding the macros to check if we are cross-compiling, and die with an
error if we are, why not simply provide a standard environment variable
for holding the name of the build machines compiler, and use that for
the test?  Some projects have manually done this (CC_FOR_BUILD, or
BUILD_CC - depending on the project).   Assuming the person doing the
cross-compiling is intelligent enough to keep their normal compiler/libs
and their cross compiler/libs at the same version, there should not be
any problems with this.

I would like to hear any reactions you have to this suggestion.

Thanks,
Ben
