Great. The patches are on the list for review. I will push them tomorrow if
nothing is raised.

I discussed this with Sebastian a week or so ago and he said there are some GOT
type references in the bootloader which must be the cause. I seem to remember
there are warnings bring printed with 2.27 but the result is not fatal.
Something must have changed.

The other solution if the bootloader is broken is to not build it. If it is
needed someone will need to fix the code and remove the warnings.
