these are linux specific constants. glibc exposes them behind
_GNU_SOURCE, but, since SEEK_* is reserved for the implementation, we
can simply define them. furthermore, since they can't be used with
fseek() and other functions that deal with FILE, we don't add them to
<stdio.h>.

Since we are now adding these flags to headers, it might make sense to
revisit [1], which I came across while looking for patches related to
SEEK_* constants.
If all we need is to restrict acceptable whence values, I can try to
make a patch.
