Re: [yocto] Yocto gdb build error on Microblaze platform

["Mark Hatle" <mark.hatle@kernel.crashing.org>]

This could be an issue with your host if the host is too old.  Unfortunately
I've not worked with the releases that are that old.

However, Xilinx did just release their 'Zeus' based rel-v2020.1 version.  That
version should work on most modern hosts (ones that Zeus works against.)  Even
if you are debugging older code the newer debugger should work, so it might be
an option for you.
