Subject: [PATCH 4.9 073/134] sparc64: only select COMPAT_BINFMT_ELF if BINFMT_ELF is set

From: Randy Dunlap <rdunlap@...radead.org>

[ Upstream commit 80bddf5c93a99e11fc9faf7e4b575d01cecd45d3 ]

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]
