This enables the newly introduced text-relative kallsyms support when building 64-bit targets. This cuts the size of the kallsyms address table in half, reducing the memory footprint of the kernel .rodata section by about 250 KB for a defconfig build.

Please remove the "if 64BIT" since s390 is always 64BIT in the meantime. Tested on s390 and everything seems still to work ;) Acked-by: Heiko Carstens <redacted>
