Only apply w/musl since while it's wrong everywhere it apparently hasn't broken things entirely w/glibc so keep things as they were. Patch regenerated from original so that it applies which isn't saying much since it's simple :). Source: https://patchwork.ozlabs.org/patch/154298/ IRC chat on #musl with Rich and others endorses this, at least at the conceptual level of no shared library should be using initial-exec TLS. Fixes various uses of libgomp that previously crashed (before 1.1.20) or encounter errors (post-1.1.20), such as pythonPackages.cython .
