While other architectures have enabled these gcc / ld options for some
time on U-Boot itself, ARM has only been doing this on SPL. Enable this
on full U-Boot as well now.

I expect this was tested on various targets?

I build-tested eldk 4.2/5.2 and the Linaro 4.7 that Ubuntu has
available, with no build failures. I spot checked what was being
dropped on am335x and some omap3/4 platforms and it looked correct, and
I did boot test am335x.
