Currently, gcc 10.0 does not compile gem5 due to an array bound error in sc_unsigned and sc_signed constructors. Previous fix only ignores array-bounds warnings for sc_unsigned.cc and sc_signed for gcc 10.1 onwards. This commit turns the ignoring array-bounds warning flag on for all gcc 10 onwards.
