+ * build process to fail. To solve this problem, the auxiliary macro MAKE_ULL(x)
+ * will add the 'ull' suffix only when the macro __LINKER__  is not defined
+ * (__LINKER__ is defined in the command line to preprocess the linker script).
+ * Constants in the linker script will not have the 'ull' suffix, but this is
+ * not a problem since the linker evaluates all constant expressions to 64 bit
+ * (assuming the target architecture is 64 bit).
