mkimage: struct stat.st_size may not be long
The component st_size of struct stat is of type off_t. Depending on the
system printing it using %ld leads to a warning:
tools/mkimage.c:438:54: warning: format '%ld' expects argument of type
'long int', but argument 5 has type
'off_t' {aka 'long long int'} [-Wformat=]
438 | "%s: Bad size: \"%s\" is not valid image: size %ld < %u\n",
| ~~^
| |
| long int
| %lld
When comparing an off_t value to a 32bit integer we should not convert to
uint32_t but to off_t which may be wider.
