Lu <hjl.to...@gmail.com> Date: Sun Aug 24 14:43:44 2025 -0700 x86: Don't put R_386_TLS_DESC/R_X86_64_TLSDESC in .rel.plt/.rela.plt Since lazy tlsdesc relocation has data races: https://sourceware.org/bugzilla/show_bug.cgi?id=27137 put R_386_TLS_DESC and R_X86_64_TLSDESC relocation in .rela.tls/.rel.tls section, instead of .rel.plt/.rela.plt section.
