1668           A 64-bit kernel is usually built using the 64-bit ELF binary object
1669           format as it's one that allows arbitrary 64-bit constructs.  For
1670           kernels that are loaded within the KSEG compatibility segments the
1671           32-bit ELF format can optionally be used resulting in a somewhat
1672           smaller binary, but this option is not explicitly supported by the
1673           toolchain and since binutils 2.14 it does not even work at all.
1674
1675           Say Y to use the 64-bit format or N to use the 32-bit one.
