This is a general autoconf problem, it uses "uname -m" which does not
describe the system adequately.

Well, "./configure --build=i486-pc-linux-gnu" works, I can live with
that for now.

Thanks for tackling this problem, previously it had not been possible to
build a 64-bit Emacs with CC="gcc -m64", but now it is (using various
--without-foo options because the only available 64-bit libraries are
libc and ncurses).
