This is an auto-filled bug because dev-perl/Net-LibIDN2 fails to compile. The issue was originally discovered on arm64, 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: Feel free to adjust the summary to clarify the exact issue..

Looks like CFLAGS got mangled in the environment prior to building this package: aarch64-unknown-linux-gnu-ld: unrecognised emulation mode: arch=native

Not necessarily a user configuration failure, but its likely to be a messy problem.
I can reproduce with perl-5.30.3-r1 too
Declaring this configuration as unsupported. Unset LD.
