I tried the same steps with export arch=armv4 and armv4t as well which 
didn't make any difference.

Can someone point me into the right direction? I would prefer stay with 
this toolchain, because I need to support a fairly old LINUX and 
userland with it and just wanna update the u-boot on my SCB9328 to get 
rid of some issues with newer JFFS2 flags not supported by my current 
1.12 uboot on the board.

I just tested: uboot 2014.01 compiles with the same settings and 
toolchain. So I guess it broke somewhere in between. I can try to 
pinpoint it if it helps.
