Comment 4 Sven B. 2019-09-17 16:22:40 UTC 
Same here. using ld.bfd instead of ld.gold works.
Comment 5 Ondrej Hojdysz 2019-09-18 06:01:02 UTC 
Same here switching from gold to bfd fixes the problem
Comment 6 Michael Schmid 2019-10-01 09:07:18 UTC 
This also seems to happen on the main stable/linux.git linux-5.3.y branch, and has done so for a few minor release versions.

Switching to the bfd linker also works around the issue there.
Comment 7 Mike Pagano gentoo-dev 2019-10-18 17:35:13 UTC 
The gold linker is not supported upstream to the point of now having a commit that will fail when attempted.

"kbuild: Fail if gold linker is detected"
