No problem, OpenEmbedded FTW!! ;-)
(it's quite easy to switch between them and build, using OE)

Would comparing the map files suffice? If I build u-boot twice (once with
binutils-2.27 and once with binutils-2.28) and add the "-N" flag to the
linking for both builds, comparing the map files I get:

	$ diff -u 2.27-with-N/u-boot.map 2.28-with-N/u-boot.map
