FLAT binaries: drop BINFMT_FLAT bad header magic warning
The warning issued by fs/binfmt_flat.c when the format handler is given a non-FLAT and non-script executable is annoying to say the least when working with FDPIC ELF objects. If you build a kernel that supports both FLAT and FDPIC ELFs on no-mmu, every time you execute an FDPIC ELF, the kernel spits out this message. While I understand a lot of newcomers to the no-mmu world screw up generation of FLAT binaries, this warning is not usable for systems that support more than just FLAT.
