Fix building packages with LTO when CONFIG_PKG_ASLR_PIE is enabled. Despite comment of PR lto/80838, it seems that GCC needs -fPIC on linker command line, even if all objects are -fPIC. This may change as PR lto/80838 is merged into 8.1 compile-tested: ar71xx, ath79 Fix commits: 6dac92a42e052f89971762173daabb7fd84742ef 8c11133c9de632dca69c8464f911d8e2716effe2 07940acc341ee9bb2887359f193625e48f36207e e7397eef69a20fc630148d0e597523e139d21c0c ef16a394d2b24a363b50b5b4720cb23fe156c9da ef96d1e34a990871c912938c336f51a510b1e32f 47b42137ce1e931ae5871952b1f98438396f5e07 73fc67b61480a3430d31de33478a1c0c2c364b9c 154c0c4006daf41e2cbb6c8b7ad5557f83dfea3e 804c51e1e661819c5a7532e66fb8a12166eef9a9 Signed-off-by: Julien Dusser <julien.dusser@free.fr>
