[PATCH OLK-6.6] kbuild: userprogs: use correct linker when mixing clang and GNU ld
by Tengda Wu 06 Aug '25

06 Aug '25

From: Thomas Weißschuh <thomas.weissschuh(a)linutronix.de> mainline inclusion from mainline-v6.17 commit 936599ca514973d44a766b7376c6bbdc96b6a8cc category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/ICRNOY Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- The userprogs infrastructure does not expect clang being used with GNU ld and in that case uses /usr/bin/ld for linking, not the configured $(LD). This fallback is problematic as it will break when cross-compiling. Mixing clang and GNU ld is used for example when building for SPARC64, as ld.lld is not sufficient; see Documentation/kbuild/llvm.rst. Relax the check around --ld-path so it gets used for all linkers.
