I even used the same --with-sysroot and --prefix switches and copied the freebsd sysroot from the linux machine to make sure I did not mistake when extracting the sysroot and copying it to the linux host in the first place. I also created another cross compiler hosted on mingw32 for freebsd from the same sourcen. It fails the same way as the linux hosted one. I also started comparing the config.log files for differences but haven't found something unusual so far.
