Since host-gdb builds fine for most people, there must be something
specific to your environment. Could you provide the details of your
host distribution + the exact Buildroot version + minimal Buildroot
defconfig that exhibits the issue so that people can reproduce ?

To be honest, I don't pretend to fully grasp the interactions between
readline, ncurses, termlib, etc. So if you want patches to be merged,
they need to come with detailed and convincing explanations :-)

Thanks a lot!

Thomas
