i found right way compile ... didn't have knowledge of how compile gcc (my first time) after reading through faq of building gcc found problem. turned out had run configure script , make outside source directory ( called gcc-build) directory list looked this

then compiled smoothly here's link faq http://gcc.gnu.org/wiki/faq#configure
