Emscripten returns ENOENT instead of ENOTDIR when opening file in nonexistent directory

[hoodmane]

a.c:

#include <fcntl.h>
#include <errno.h>
#include <string.h>
#include <stdio.h>

int main(void) {
    open("directory-that-does-not-exist/b", O_RDWR | O_CREAT | O_EXCL);
    printf("Error %d: %s\n", errno, strerror(errno));
}

Run it

$ gcc a.c
$ ./a.out
Error 20: Not a directory
$ emcc a.c
$ node a.out.js
Error 44: No such file or directory

Desired behavior

Emscripten should return ENOTDIR not ENOENT

Okay well now I'm trying it again and getting Error 2: No such file or directory with gcc.
