It's a relocation that won't work on a PIE build, and your system is probably configured to build using PIE even if not requested. Can you try adding -no-pie to the builds that use thunks.S? (Given how thunks.S works, it'll also fail if relocated above 4G, so even eliminating the relocations may not be enough.)
