Heiko Carstens 148f1678f0 [S390] sparsemem: use SPARSEMEM_STATIC if !64BIT.
In case of !64BIT kernel we end up with a zero sized mem_section array.
This happens because NR_MEM_SECTIONS is smaller than SECTIONS_PER_ROOT
but we have:

#define NR_SECTION_ROOTS (NR_MEM_SECTIONS / SECTIONS_PER_ROOT)

and

struct mem_section *mem_section[NR_SECTION_ROOTS];

So fix this by selecting SPARSEMEM_STATIC which makes sure
that SECTIONS_PER_ROOT is 1.
