Crosstool-NG缺少依赖性

Question

我正在尝试使用工具链Crosstool-NG.我使用Crosstool-NG 1.22.0的OS X 10.11.4.

我安装使用homebrew,所以我不确定为什么我缺少依赖项.当我尝试构建时,这是我的输出:

$ ct-ng build
[INFO ]  Performing some trivial sanity checks
[INFO ]  Build started 20160504.172530
[INFO ]  Building environment variables
[ERROR]  Missing: 'x86_64-apple-darwin15.4.0-gcj' or 'x86_64-apple-darwin15.4.0-gcj' or 'gcj' : either needed!
[ERROR]   
[ERROR]  >>

[ERROR]  >>
[ERROR]  >>  For more info on this error, look at the file: 'build.log'
[ERROR]  >>  There is a list of known issues, some with workarounds, in:

[ERROR]   
[ERROR]  (elapsed: 0:01.00)
[00:02] / make: *** [build] Error 1

如果需要,我可以附加我的.config文件,但我相信错误是在此之前.

我已经尝试过跑:

$ brew install gcc --with-java

但错误仍然存​​在.我一直在网上关注一些教程,主要是这个,所以也许它有错误.我检查了build.log输出,它几乎与shell输出相同.这个问题有一个已知的解决方案,还是我忘记了某个步骤？
