I am running into the same problem. Me wonders which patch/change triggers this problem. I am using the same toolchain since I started to work with u-boot and it fails with the latest rc.
Maybe Linaro started using a hard-float configuration only recently?
For what it's worth, i just ran a git bisect on this issue today, as this compiler worked fine with v2013.10
toolchain: arm-linux-gnueabihf-gcc (crosstool-NG linaro-1.13.1-4.8-2013.10 - Linaro GCC 2013.10) 4.8.2 20131014 (prerelease)
762a88ccf8540948fbf8c31b40a29d1e0684a25b is the first bad commit commit 762a88ccf8540948fbf8c31b40a29d1e0684a25b Author: Pierre Aubert p.aubert@staubli.com Date: Thu Sep 19 17:48:59 2013 +0200
mx6: compute PLL PFD frequencies rather than using definesThat commit introduces a 64-bit division without using the lldiv() function, which pulls in previously unused libgcc stuff.
Try this patch:

Thanks Måns!
That fixed it...
