Update -fno-pie to only be added when relevant. This fixes native_posix builds on Debian hosts. * Debian and other Linux distributions have ld with --warn-textrel as default. * The option generates a warning when linking on x86. * The warning make scripts/twister fail because we treat all warnings as error. * The warning is issued when no PIE objects are linked against PIE library. * PIE (Position Independent Executable) or not can be seen with the following command. * When you want to generate non PIE, link with `-no-pie.` Non PIE $ readelf -l build/zephyr/zephyr.elf | grep 'Elf file type is' Elf file type is EXEC (Executable file) PIE $ readelf -l /lib/x86_64-linux-gnu/libc.so.6 | \ grep 'Elf file type is' Elf file type is DYN (Shared object file) Issue #35244 Signed-off-by: Yuval Peress <peress@google.com>
