在FreeBSD中建立Gold链接器

我按照 http://llvm.org/docs上的步骤操作/GoldPlugin.html#lto-how-to-build 在FreeBSD上构建gold插件，但是！

I followed the steps on http://llvm.org/docs/GoldPlugin.html#lto-how-to-build to build the gold plugin on FreeBSD but !

有一个指向错误屏幕截图的链接： http://postimg.org/image/anlpuufbl/

Heres a link to the screenshot of the error:http://postimg.org/image/anlpuufbl/

这是它显示的错误消息，所以我也无法得到ld-new。
我选中，并且没有在etc / make.conf中设置CFLAGS。

This is the error message that it shows and so I am also unable to get ld-new. I checked and no CFLAGS were set in etc/make.conf.

如何继续安装？
我使用FreeBSD 10.1提供的deault clang版本。

How to proceed with the installation? I am using the deault clang version supplied with FreeBSD 10.1.
