Please try u-boot-dm/testing. This seems to be a different problem:
avr32: + grasshopper+lib/time.c:20: warning: register used for two global register variables
I am using the avr32 toolchain from kernel.org, and couldn't see the problem. gcc version 4.2.4-atmel.1.1.3.avr32linux.1
For me, I cannot reproduce the build error too with buildman. I am using the same toolchain as Thomas.
Would you please offer the link to download the avr32 toolchain you used?
It is avr32-buildroot-linux-uclibc-gcc

So fairly old.
I'm not sure if I built it or downloaded it - it was a while ago.
So perhaps this is a toolchain problem. But still I don't think we want to declare the global_data pointer in a header file.
Applied to u-boot-dm, replacing the earlier v2 patch.
