If anyone has any objections, please let me know. ------------------ From: Jason Gunthorpe [ Upstream commit 4bcfe29021993cb167fd9bbdb849f7d7247a166f ] Use if_changed_rule so rule_cc_o_c runs cmd_save_c_flags for the kunit objects. Without the saved flags CONFIG_LTO_CLANG_THIN_DIST runs the ThinLTO backend with no --target and generates x86_64 code from arm64 bitcode.
