From fd526e121c4d6f71aed82d21a8b8277b03e60b43 Mon Sep 17 00:00:00 2001 From: Tony Ambardar Date: Tue, 8 Oct 2024 21:07:20 -0700 Subject: selftests/bpf: Fix cross-compiling urandom_read Linking of urandom_read and liburandom_read.so prefers LLVM's 'ld.lld' but falls back to using 'ld' if unsupported. However, this fallback discards any existing makefile macro for LD and can break cross-compilation. Fix by changing the fallback to use the target linker $(LD), passed via '-fuse-ld=' using an absolute path rather than a linker "flavour".
