linker problem with xip kernel and recent toolchains

we've just discovered a linker problem with newer toolchains, that
support --build-id and xip kernels. The resulting vmlinux is about 13
MiB big, but the xipimage ~2GiB.

A look at the vmlinux's objdump shows that the .notes section is around
2 GiB and it's placed by the linker script into the RAM. With the ROM
starting at 0x0 this results into a ~2 GiB big image.

After discarding the .notes section in the objcopy (see patch below) the
resulting binary images has a proper size again.

Could you please send me the configuration you're using to get the XIP
kernel? I'll try to get my head around this problem and check how other
architectures are dealing with the problem.

Thanks!
