Browse Source 
Fix the following compiler warning on 32bit:

    -nostdlib -nostdinc -static -Isysroot/i386/include nolibc-test.c nolibc-test-linkage.c -lgcc
  nolibc-test.c: In function 'expect_str_buf_eq':
  nolibc-test.c:610:30: error: format '%lu' expects argument of type 'long unsigned int', but argument 2 has type 'size_t' {aka 'unsigned int'} [-Werror=format=]
    610 |         llen += printf(" = %lu <%s> ", expr, buf);
        |                            ~~^         ~~~~

        |                            %u
