1660           A 64-bit kernel is usually built using the 64-bit ELF binary object
1661           format as it's one that allows arbitrary 64-bit constructs.  For
1662           kernels that are loaded within the KSEG compatibility segments the
1663           32-bit ELF format can optionally be used resulting in a somewhat
1664           smaller binary, but this option is not explicitly supported by the
1665           toolchain and since binutils 2.14 it does not even work at all.
1666
1667           Say Y to use the 64-bit format or N to use the 32-bit one.
1668
1669           If unsure say Y.
