linux安装apache错误：configure: error: /bin/sh build/config.sub failed的解决办法。

上图：
第一次遇到这个问题，实在无奈，找遍了是没找到问题解决办法。
最后动手解决如下：
./configure \
--prefix=/application/apache2.2.27 \
--enable-deflate \
--enable-expires \
--enable-headers \
--enable-modules=most \
--enable-so \
--with-mpm=worker \
--enable-rewrite \
错误：如下：
configure: WARNING: you should use --build, --host, --target
configure: WARNING: invalid host type:
--enable-so \
--with-mpm=worker \
--enable-rewritechecking for chosen layout... Apache
checking for working mkdir -p... yes
checking build system type... config.sub: missing argument
Try `config.sub --help' for more information.
configure: error: /bin/sh build/config.sub failed
然后我再去执行/bin/sh ./include/config.sub，结果错误是这样子的：
[root@servers httpd-2.2.27]# /bin/sh config.sub
config.sub: missing argument
Try `config.sub --help' for more information.
提示参数不够，试试去掉所有参数再进行环境检查：发现万事OK！没问题！
然后可以确定问题在参数方面，然后我开始一个个去掉参数：发现问题出现在--enable-deflate \这个上面，故这个有问题。
最后对调参数：用如下测试：参数放在倒数第二个再次环境测试！结果发现通过了！其实问题出现在\后面有空格，去掉空格再编译：
./configure \
--prefix=/application/apache2.2.27 \
--enable-expires \
--enable-headers \
--enable-modules=most \
--enable-so \
--with-mpm=worker \
--enable-deflate \
--enable-rewrite \
至此问题得以解决！
