Subject: [PATCH] sparc64: only select COMPAT_BINFMT_ELF if BINFMT_ELF is set

Currently COMPAT on SPARC64 selects COMPAT_BINFMT_ELF unconditionally,
even when BINFMT_ELF is not enabled. This causes a kconfig warning.

Instead, just select COMPAT_BINFMT_ELF if BINFMT_ELF is enabled.
This builds cleanly with no kconfig warnings.

WARNING: unmet direct dependencies detected for COMPAT_BINFMT_ELF
  Depends on [n]: COMPAT [=y] && BINFMT_ELF [=n]
  Selected by [y]:
  - COMPAT [=y] && SPARC64 [=y]
