To debug it, let's add '-Wl,--verbose' at the end of your command and you should be able to see where the linker is looking for libraries. Also, the linker script will be printed. You should see it try your directory first tmp/sysroots/qemux86-64/usr/lib/, and then fall through the default ones with the sysroot prefix added and, at the end, the system ones: /lib:/usr/lib.
