[PATCH 6/8] SPU add some file related calls
Add support for the following spu functions, implemented via assist calls:
void sync(void)
int fsync(int fd)
int fdatasync(int fd)
int dup2(int oldfd, int newfd)
int lockf(int fd, int cmd, off_t len)
int truncate(const char *path, off_t length)
newlib ChangeLog:
2007-06-18 Patrick Mansfield <patmans@us.ibm.com>
* libc/include/sys/unistd.h: Add lockf prototype and related
defines; expose ftruncate, truncate and sync prototypes.
