The new command "grub-fstest" may not work for large image files or
/dev/sdX devices on 32-bit platforms.
Legacy C89 functions fseek() and ftell() always use "long" as offset
type. The attached patch changes this to fseeko() and ftello() which use
off_t. These are part of POSIX, so new ./configure stuff should be not
necessary.

* util/hostfs.c (grub_hostfs_open): Use fseeko and ftello
instead of fseek and ftell to support large files.
(grub_hostfs_read): Likewise.
