That looks more reasonable to me and it is in line with what was
suggested on the linux-arm-kernel mailing-list, see
As you can see from the linked thread, the compiler we ended up with
works nicely for userspace, but it cannot be used to build a kernel. It
may be a good idea to set BR2_GCC_TARGET_ABI to aapcs-linux even if
BR2_iwmmxt is selected.

What exactly do you want me to try? I guess I would have to remove
my .config and go thru menuconfig, select ARM iwmmxt and then check what
gets sets for BR2_GCC_TARGET_TUNE, BR2_GCC_TARGET_ARCH and
BR2_GCC_TARGET_ABI? Is that correct?
