This adds LIBC_CONF_PRINTF_MODULAR, which causes floating point support (later, others) to be weakly linked into the implementation. __printf_modular becomes the main entry point of the implementaiton, an printf itself wraps __printf_modular. printf it also contains a BFD_RELOC_NONE relocation to bring in the float aspect. See issue #146159 for context.
