2. 用qt自带qconfig工具进一步裁剪
 注意： 我的当前目录是 qt-everywhere-opensource-src-4.8.7/，x86版本安装在 /opt/qt-4.8.7-x11/
(1)qconfig 工具编译：
    $ cd tools/qconfig
    $ /opt/qt-4.8.7-x11/bin/qmake
    $ make
(2)qconfig工具执行：
    $./ tools/qconfig/qconfig
      之后要选择src/corelib/global/qfeatures.txt
(3)在已有的配置方案里选择一个，qconfig软件里 打开qconfig-minimal.h，qconfig-nacl.h，qconfig-small.h，qconfig-medium.h，qconfig-large.h，qconfig-dist.h(裁剪量由多到少)中的任意一个，在此基础上进行裁剪。裁剪后，SAVE AS即可，比如：qconfig-cwd.h，这跟上面的-qconfig cwd对应。
(4)最后重新 用上述脚本编译，注意 由于qt各个都是 关联的，所以配置完后，经常编译通不过，这时需要重新配置qconfig，再编译。可能是这个软件做的还不够好，跟configure选项有冲突。

        [additional platform specific options (see below)]

Installation options:

    -qpa [name] ......... This will enable the QPA build.
                          QPA is a window system agnostic implementation of Qt.
                          If [name] is given, sets the default QPA platform (e.g xcb, cocoa).

 These are optional, but you may specify install directories.

    -prefix

...... This will install everything relative to
                         (default /usr/local/Trolltech/Qt-4.8.7)

  * -prefix-install .... Force a sandboxed "local" installation of
                         Qt. This will install into
                         /usr/local/Trolltech/Qt-4.8.7, if this option is
                         disabled then some platforms will attempt a
                         "system" install by placing default values
                         in a system location other than PREFIX.

 You may use these to separate different parts of the install:

    -bindir

......... Executables will be installed to
                            (default PREFIX/bin)
    -libdir ......... Libraries will be installed to
                            (default PREFIX/lib)
    -docdir ......... Documentation will be installed to
                            (default PREFIX/doc)
    -headerdir ...... Headers will be installed to
                            (default PREFIX/include)
    -plugindir ...... Plugins will be installed to
                            (default PREFIX/plugins)
    -importdir ...... Imports for QML will be installed to
                            (default PREFIX/imports)
    -datadir ........ Data used by Qt programs will be installed to
                            (default PREFIX)
    -translationdir . Translations of Qt programs will be installed to
                            (default PREFIX/translations)
    -sysconfdir ..... Settings used by Qt programs will be looked for in
                            (default PREFIX/etc/settings)
    -examplesdir .... Examples will be installed to
                            (default PREFIX/examples)
    -demosdir ....... Demos will be installed to
                            (default PREFIX/demos)

 You may use these options to turn on strict plugin loading.

    -buildkey .... Build the Qt library and plugins using the specified
                         .  When the library loads plugins, it will only
                         load those that have a matching key.
