-------------------------------------------------

This reverts commit 41026c34.

Since commit 7de3ab4c ("arm64: introduce binfmt_elf32.c"), whether it
is ILP32 or AARCH32_EL0, fs/compat_binfmt.c is not used for arm64. So it
is not reasonable to be default y for COMPAT_BINFMT_ELF and revert it to
to make all architectures to individually select it.
