Update config.guess and config.sub for AArch64 (ARM64)
Description
ふと cross compile のやり方を知ってしまって、いろいろと試していると、
AArch64 (ARM64) で configure で失敗することに気がつきました。

Select "Target Architecture (i386) --->" and select "AArch64".
Then select and .

configure: WARNING: if you wanted to set the --build type, don't use --host.
If a cross compiler is detected then cross compile mode will be used

どうも、config.guess と config.sub を更新する必要があるようです。

.ext/include/aarch64-linux/ruby/config.h updated
verconf.h updated
ruby library version = 2.1.0
configure: creating ./config.status
config.status: creating GNUmakefile
config.status: creating Makefile
config.status: creating ruby-2.1.pc
% make
% make install DESTDIR=$B/root
config.guess と config.sub を更新すれば、install まではいきます。
(実行してないのでその先はわかりません)
