Sorry, are you working for the AVR or AVR32? They are two totally
different processors, AVR has GCC support in mainline but not in
crosstool-ng. AVR32 does not have support in mainline GCC but does in
crosstool, thanks to several megabytes of patches for gcc-4.2.2,
binutils-2.18 and newlib-1.17

Mind you, I can't see GCC running on the 8-bit AVR processors, so I
assume you mean AVR32, in which case you might start from here:
http://spaces.atmel.com/gf/project/ct-ng/
which has patches for AVR32 for more versions, up to gcc-4.4.7.

That said, the current AVR32 stuff in crosstool-ng only supports
newlib on bare-metal targets if I understand correctly. What operating
system environment platform are you wanting the ct-ng-generated
compiler to run on?
  I think the AVR32 patches have support for uclinux (or had... I fear
I may have diked that part out while pruning the patches for my
project).  Do you maybe have linux/uclibc running on AVR32?
