    generic: enable RELR relocations
    
    RELR is a relocation packing format for relative relocations.
    
    Linux has supported using it for ARM64 since 5.4, and more recently
    for LoongArch as well.
    
    It requires compatible tooling as well, so only with binutils 2.43
    TOOLS_SUPPORT_RELR is set and thus RELR available.
    
    RELR should always decrease the binary size and while testing this
    the default build for Dynalink WRX-36 (qualcommax/ipq807x) reduced
    the compressed kernel size by 38k and uncompressed one by 640k.
    
    So, lets enable it in the default config.
