This is a 100% copy of what is in meta-rockchip.  See
https://git.yoctoproject.org/cgit/cgit.cgi/meta-rockchip/tree/recipes-devtools/gcc-arm-none-eabi/gcc-arm-none-eabi-native_9-2019-q4-major.bb

So, they should get the credit for actually doing the work.  I'll
modify to incorporate the suggestions, assuming JPEW is in agreement.

Looks like it should be (based on the website)
https://developer.arm.com/-/media/Files/downloads/gnu-rm/9-2019q4/gcc-arm-none-eabi-9-2019-q4-major-x86_64-linux.tar.bz2

I'll come out with a v2 shortly.  Thanks for the feedback.

Thanks,
Jon
