It appears to be attempting to build the regex function of libiberty for the target, and failing because there isn't a target system library available. I'm not sure why 4.4.3 wants to build that when 4.3.3 did not. My configuration options are based on what Codesourcery uses for arm-none-eabi in their 2009q3 toolchain.
