From 97ed403650c3fdbf47c14ca71d4c0b0d55a25a44 Mon Sep 17 00:00:00 2001 From: Arthur Heymans Date: Fri, 23 Feb 2024 16:44:37 +0100 Subject: util/xcompile: Use a more complete clang target When the compiler is used as a linker frontend clang tries to match the target string with what it supports internally. If it's not sufficiently complete it will forward linking to GCC which is not desirable. This is necessary when doing LTO with clang.
