selftests/bpf: Fix cross-compiling urandom_read
[ Upstream commit fd526e121c4d6f71aed82d21a8b8277b03e60b43 ]
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".
