Subject: [PATCH v2 03/10] tools/nolibc: stdint: use int for size_t on 32bit

Otherwise both gcc and clang may generate warnings about type
mismatches:

sysroot/mips/include/string.h:12:14: warning: mismatch in argument 1 type of built-in function 'malloc'; expected 'unsigned int' [-Wbuiltin-declaration-mismatch]
   12 | static void *malloc(size_t len);
      |              ^~~~~~
