I've been trying to build a WGT624V3 kernel but it fails at the very end 
when it links everything together to make the kernel:

/usr/src/../tools/bin/mipsel--netbsd-ld: athhal.o: compiled for a big 
endian system and target is little endian
/usr/src/../tools/bin/mipsel--netbsd-ld: athhal.o: endianness 
incompatible with that of the selected emulation
/usr/src/../tools/bin/mipsel--netbsd-ld: failed to merge target specific 
data of file athhal.o

build command:
$ cd /usr/src
$ rm -Rf /usr/obj
$ rm -Rf /usr/tools
$ ./build.sh -T ../tools -O ../obj -m evbmips -a mipsel -U tools
$ ./build.sh -T ../tools -O ../obj -m evbmips -a mipsel -U kernel=WGT624V3 
===> build.sh command: ./build.sh -T ../tools -O ../obj -m evbmips -a 
mipsel -U kernel=WGT624V3

srcs were fetched from cvs last night.
