I could be too, but the (few) times I've seen any discussion of this on
the autoconf mailing list, it agrees with my impression.  autoconf isn't
designed to handle this.

You can use the --with-build-cc configure option to tell the configure
script explicitly what to set BUILD_CC to (as well as related stuff
normally not needed since it's using the default C runtime).
