+Subject: kbuild: userprogs: use correct linker when mixing clang and GNU ld
+To: gregkh@linuxfoundation.org, sashal@kernel.org
+Cc: stable@vger.kernel.org, nathan@kernel.org, thomas.weissschuh@linutronix.de
+Message-ID: <20250821183106.1268616-1-nathan@kernel.org>
+
+From: Thomas Weißschuh <thomas.weissschuh@linutronix.de>
+
+commit 936599ca514973d44a766b7376c6bbdc96b6a8cc upstream.
+
+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.
