    esp32c3_rom.ld:  Add some of the string.h functions to the linker
    script.
    
    These functions are strongly declared and thus will be used instead of
    any other implementation.  Furthermore, necessary Kconfig options are
    selected to avoid building those function from NuttX's C library.
