libgcc2.i from xgcc

Same source compiled fine with amd64 native tools.

GCC tested are:
1. xgcc (GCC) 7.0.0 20161105 (experimental) (github: trunk@241870)
2. gcc (Debian 6.2.0-11) 6.2.0 20161103

System:
/usr/bin/qemu-arm-static
Debian sid chroot

Configure:
1. ../configure
That resulted to config.status including
--enable-languages=c,c++,fortran,lto,objc
