[PATCH] binfmt_elf: Quiet GCC-4.6 'set but not used' warning in load_elf_binary()

From: David Daney
Date: Mon Jan 24 2011 - 18:04:22 EST

With GCC-4.6 we get warnings about things being 'set but not used'.

In load_elf_binary() this can happen with reloc_func_desc if
ELF_PLAT_INIT is defined, but doesn't use the reloc_func_desc

Quiet the warning/error by marking reloc_func_desc as __maybe_unused.
