When COMPAT is enabled and BINFMT_ELF is disabled, it results in the following Kbuild warning: WARNING: unmet direct dependencies detected for COMPAT_BINFMT_ELF Depends on [n]: COMPAT [=y] && BINFMT_ELF [=n] Selected by [y]: - COMPAT [=y] && SPARC64 [=y] The reason is that COMPAT selects COMPAT_BINFMT_ELF without depending on or selecting BINFMT_ELF while COMPAT_BINFMT_ELF depends on BINFMT_ELF. This can also fail building the kernel as demonstrated in a bug report. Honor the kconfig dependency to remove unmet direct dependency warnings and avoid any potential build failures.
