common.mak: Set default C/C++ standard to gnu11/gnu++11

Browse Source 
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.
