In my opinion, the best way for getting what you need is to use crosstool-ng:

https://github.com/crosstool-ng/crosstool-ng

You can clone the repo, build and install the program.
Then, you can use ct-ng for configuring the build with the platform
you want and finally start the creation.
When the process finishes, you will find your cross compiler into the
"x-tools" directory, inside your $HOME.
When you get it, it is very easy to create a cross compiler: with this
tool, I created an arm-none-eabi with NEWLIB, an aarch64 android cross
compiler with NDK and an armhf linux cross compiler.
I suggest you to do a try with this tiny thing.
Please note that after you start the build, the tool automatically
downloads the tar files with the sources that it needs, unless it
already finds them in its directory, so be careful if you have a
limited amount of internet traffic available.

Sincerely.
