[Bug libc/5400] New: Assume fdatasync syscall always exists

[aurelien at aurel32 dot net]

The fdatasync syscall is present for a very long time in the linux kernel 
(since pre 2.0 kernels) on all architectures except alpha. On this architecture 
it has been recently added to the 2.6.22 kernel.

This causes fdatasync() to fail on a glibc compiled against a 2.6.22 kernel run 
on pre 2.6.22 kernel.

Patch will follow.

Alpha is not in the main tree anymore since we have no maintainer.  Somebody has
to step up and volunteer to be the maintainer of the alpha ports tree or nothing
will happen.

Richard Henderson fixed this with commit c735022ded3 to glibc-ports.git. Marking
as fixed.

Yeah, I'm wrong it looks like. Sorry about that.

Matt: are you sure ?  commit c735022ded3fb7967bf24b9f385cd7f8f1cdea77 updated
the fcntl.h header to add the missing bits.  i don't see any fdatasync related
changes in there.

we probably want to move the new fdatasync.c to
ports/sysdeps/unix/sysv/linux/alpha/ to localize the noise to alpha
