Looks like it's enough to just add wrappers pointing to the
corresponding SYS_FSTATAT{,64} or SYS_NEWFSTATAT syscall. Add a test to
verify that assumption which checks that the returned stat data matches
what is returned by Stat/Lstat.
Also add the AT_NO_AUTOMOUNT constant which may be used for the flags
parmeter.

In order to make conversion to string easier, change the Utsname
members from int8 array to byte array.
Also add a test on Linux for Uname and the string conversion of the
Utsname members.

Analog to the runtime package, Select should be using newselect
instead of select. This change addresses this problem and regenerates
zsyscall_linux_* for ppc64 and ppc64le.

Currently Linux' fchmodat(2) syscall implementation doesn't support the
flags parameter (though it might in future versions [1]). Fchmodat in
x/sys/unix takes the parameter and (wrongly) passes it on to the syscall
which will ignore it.
According to the POSIX.1-2008 manual page [2], AT_SYMLINK_NOFOLLOW is
the only valid value for the flags parameter and EOPNOTSUPP should be
returned in case changing the mode of a symbolic link is not supported
by the underlying system. EINVAL should be returned for any other value
of the flags parameter.

Change the Fchmodat implementation accordingly and also add the
corresponding test.

This CL adds basic integer get/set functions which wrap a generic
ioctl call. The API is similar the one introduced for solaris/amd64
in CL 14587, but the request parameter has been changed to a uint
instead of an int. This makes requests with a number larger than the
maximum signed 32-bit integer work on linux/386.
For consistency, the solaris/amd64 API has also been updated to make
use of a uint instead of an int for the request number.
