s390-tools doesn't define a common C/C++ standard at the moment. Set the standard to gnu11/gnu++11, which is also used by the Kernel, and establish a common baseline for all tools. The -std flag is added to ALL_CFLAGS and ALL_CXXFLAGS to avoid losing it in case CFLAGS are set by an outside entity. It is also added to CLAGS_FOR_BUILD for this one special cross build case. The -std flag is removed from all tools that set it manually until now.
