perf: Add LDFLAGS to allow build of old kernels without patching
The LDFLAGS is required or some old kernels fails due missing symbols and this is preferred than requiring patches to every old supported kernel. Fixes [YOCTO: #5221] Signed-off-by: Otavio Salvador <otavio@ossystems.com.br> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
