This is an auto-filled bug because app-emulation/coldfire calls ld directly. The issue was originally discovered on amd64, but it may be reproducible on other arches as well. If you think that a different summary clarifies the issue better, feel free to change it. Attached build log and emerge --info. NOTE: If you think it doesn't make sense fix these type of issues, I'd like to point out that won't be possible use a different LINKEr implementation (like llvm-link) by setting the LD variable. So this issue has been reproduced by setting the LD variable to x86_64-pc-linux-gnu-ld and by removing the /usr/bin/ld binary.
