I found the file where it is specified which binutils versions are 
available for a certain architecture.

It is in /buildroot/toolchain/binutils/config.in

In the older version (allowing to select 2.17) there is:

	config BR2_BINUTILS_VERSION_2_17
		depends on BR2_avr32 || !BR2_nios2 && BR2_DEPRECATED
		depends on BR2_EXT_BINUTILS_VERSION_2_17
		bool "binutils 2.17"

where as in the most recent snapshot it is:

	config BR2_BINUTILS_VERSION_2_17
		depends on BR2_avr32 || !BR2_nios2
		depends on BR2_DEPRECATED && !BR2_avr32
		depends on BR2_EXT_BINUTILS_VERSION_2_17
		bool "binutils 2.17"

The later configuration makes it impossible to select 2.17 as a binutils 
version for avr32. As there is no other binutils version that is allowed 
to be selected for avr32, it is simply impossible to select a binutils 
version at all.
I've replaced this section of the file by the older one and now I can 
select 2.17 also on the most recent snapshot.

Unfortunately, the problems described in "[Buildroot] avr32: lbipthread 
problem" remain the same also for the most recent snapshot. I'm stuck in 
the make process at the generation of libgomp.
