The package =sys-libs/libcxx-17.0.4 fails to link with ld.bfd and USE +abi_x86_32. Perhaps linked to a recent update to glibc 2.38... Reproducible: Always Steps to Reproduce: 1. Attempt to build =sys-libs/libcxx-17.0.4 with USE +abi_x86_32 2. 3. Actual Results: Linker (ld.bfd) failures, of the nature: undefined reference to `__isoc23_*` Expected Results: Clean build I have a system with +abi_x86_32 enabled globally.
Created attachment 874332 [details] sys-libs/libcxx build log, with USE +abi_x86_32 Log file for failed package build (ld.bfd linking errors), with USE +abi_x86_32.
