OK, thanks. At present, gcc 6.0 is the latest in master branch.

After check fedora released toolchain (gcc 4.9.1, binutils 2.25), it has
no issue (support static variable in our case). So this patch can be
dropped, and I shall try:

 - Use the same configuration parameters of fedora released toolchain to
   build the upstream latest cross toolchain again, and try.

 - If it still has issue (not support static variable), I shall try to
   fix it.


Thanks.
