Not really. I currently "solve" the problem by using the patch below,

this, it works fine for me, but I understand that this maybe isn't a
good fix to the problem.

Subject: [PATCH] Make arm926ejs use -mabi=apcs-gnu to avoid EABI problems

Using -mabi=apcs-gnu allows Marvell Kirkwood-based boards to boot with
the EABI changes introduced in commit
