On attempt to build ARC toolchain on the host with gcc 6.1 I saw the same failure as described in https://gcc.gnu.org/bugzilla/show_bug.cgi?id=69959 This change adds a back-port of the fix from upstream gcc, see https://gcc.gnu.org/viewcvs/gcc?view=revision&revision=233572 Note the fix is already a part of gcc-5.4 and gcc-6.1 so no need for the same fix for others.
