With my new build cross-compiler, It can work for sh architecture own config files, but can not work with allmodconfig (I will analyze it). The cross-tools which I build is: [root@dhcp122 linux-next]# sh3-gchen-linux-gnu-ld -v GNU ld (crosstool-NG hg+unknown-20130731.103227) 2.22 [root@dhcp122 linux-next]# sh3-gchen-linux-gnu-gcc -v Using built-in specs.
