    Build: Drop -no-pie from EMBEDDED_EXTRA_CFLAGS
    
    This breaks all Clang builds, as demostrated by Gitlab CI.
    
    Contrary to the description in ecd6b9759919, -no-pie is not even an option
    passed to the linker.  GCC's actual behaviour is to inhibit the passing of
    -pie to the linker, as well as selecting different cr0 artefacts to be 
linked.
    
    EMBEDDED_EXTRA_CFLAGS is not used for $(CC)-doing-linking, and not liable to
    gain such a usecase.
