My best guess is that it's carried over from my 2.4.x days.

A quick Google search shows several U-Boot image building tutorials
that do this.

e.g.  http://www.ronetix.at/an008_ARM_Linux_Debugging.html

It was never a problem until GCC v4 was required for a clean kernel
build but I will certainly review my build scripts with this in mind.
:)

I only do kernel work every few years as needed for the company
product, so I tend to play catchups on these changes.
