It is really the original sh-linux-gnu- compiler's issue (not only for
allmodconfig, but also for sh own config files).

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

Next, I will make a confirmation for sh64 compiler whether is OK or not.

Welcome any members' suggestions or completions.

Thanks.
