Re: ld is unable to link the Linux kernel for ARM

Hi Nicolas,

Right.  foo.o is an empty archive and bar.o is an empty object file.
Hence the linker cannot find a section onto which it can attach the
interworking stubs.  Of course given that the input is empty  the
linker is not going to have to create any stubs, so please try the
patch below.

Cheers

        * emultempl/armelf.em (arm_elf_before_allocation): Replace ASSERT
        with a test for a NULL bfd_for_interworking.
