For reference: https://bugs.gentoo.org/832677, https://bugs.gentoo.org/832676 Due to tbb's build settings, it will successfully produce so files even if the necessary symbols cannot be resolved. A patch was recently merged to master upstream which prevents these symbols from being included in the build if GLIBC is not detected on Linux (https://github.com/oneapi-src/oneTBB/pull/748/files). Reproducible: Always Steps to Reproduce: 1. Emerge dev-cpp/tbb on a musl libc system. 2. Attempt to emerge something which uses tbb, like sys-devel/mold. Actual Results: Linking fails due to the undefined symbols noted above. Expected Results: Build should succeed. I have extracted the patch merged upstream and will add it as soon as this report is submitted.

In theory, may not be needed (shouldn't be) given we've fixed our packaging of libucontext, but let's do this anyway as the fix is upstream, and it avoids possible otehr issues.
