Commit 1e4c64b71c9b ("mm/memblock: Add "reserve_mem" to reserved named memory at boot up") introduce usage of isspace(). In kernel source code, memblock.c include the definition by debugfs.h/seq_file.h/string_helpers.h/ctype.h. Since it already has ctype.h in tools, let complete the include chain to fix the build error.
