You already found it by yourself: the 2018 version stops at gcc-8; gcc-9 
was added in Feb 2020. [1]

I can think of three options:

(1) Patch your current Buildroot installation (no support)
(2) Upgrade to Buildroot 2020.02 (may break your target firmware)
(3) Install gcc 8.x on your host machine

Any specific reason for the 2018.11 version?

Kind regards,
Andreas
