jemalloc 编译出错

linux编译jemalloc，按照install.md的安装说明：

Building and installing a packaged release of jemalloc can be as simple as
typing the following while in the root directory of the source tree:

    ./configure
    make
    make install

If building from unpackaged developer sources, the simplest command sequence
that might work is:

    ./autogen.sh
    make dist
    make
    make install

Note that documentation is not built by the default target because doing so
would create a dependency on xsltproc in packaged releases, hence the
requirement to either run 'make dist' or avoid installing docs via the various
install_* targets documented below.

因为没有configure文件，所以只能选择第二种。

生成相应的.a文件后使用它，报错:

undefined reference to `je_malloc'

undefined reference to `je_realloc'

.... ...

解决方案：
./autogen.sh 的时候带上参数！即 "./autogen.sh --with-jemalloc-prefix=je_" 重新生成.a文件后不再报错
