[AArch64] Return the correct size for TLSDESC_CALLSEQ
The branch relaxation pass is computing the wrong offsets because it assumes
TLSDESC_CALLSEQ eats up 4 bytes, when in fact it is lowered to an instruction
sequence taking up 16 bytes. This can become a problem in huge files with lots
of TLS accesses, as it may slowly move branch targets out of the range computed
by the branch relaxation pass.

If you create a zfs child folder, zfs send returns an error when a recursive
incremental send is done between two snapshots made prior to the folder
creation.
The problem can be reproduced with the following steps.
root@zfs:/# zfs create pool/test
root@zfs:/# zfs snapshot pool/test@snap1
root@zfs:/# zfs snapshot pool/test@snap2
root@zfs:/# zfs create pool/test/child
root@zfs:/# zfs send -R -I pool/test@snap1 pool/test@snap2 > /dev/null
WARNING: could not send pool/test/child@snap2: does not exist
WARNING: could not send pool/test/child@snap2: does not exist
root@zfs:/# echo $?
1
root@zfs:/# zfs snapshot -r pool/test@snap3
root@zfs:/# zfs send -R -I pool/test@snap1 pool/test@snap3 > /dev/null
root@zfs:/# echo $?
0
root@zfs:/# zfs send -R -I pool/test@snap2 pool/test@snap3 > /dev/null
root@zfs:/# echo $?
0
Since pool/test/child was created after snap2, zfs send should not expect snap2
to be in pool/test/child when doing a recursive send. It should examine the
compare the creation time of the snapshot and each child folder to decide if
the folder will be sent. The next incremental send between snap2 and snap3
would properly create the child folder and snap3 which first appears in the
child folder.
The problem is identical if '-i' is used instead of '-I'.

Currently zfsdev_ioctl, when confronted by a request with the FKIOCTL flag set,
skips all processing of secpolicy functions. This means that ZFS is not doing
any kind of verification of the credentials or access rights of the caller and
assuming that (as it is an in-kernel client) all such checks have already been
done.
This turns out to be quite a dangerous assumption, especially with respect to
sdev. In general I don't think it's particularly reasonable to offload this
enforcement of access rights onto other kernel subsystems when ZFS has some
particular local semantics in this area (delegated datasets etc) and does not
provide any kind of API to allow other subsystems to avoid code duplication
when doing it. ZFS should apply its normal access policy to requests from
within the kernel, and callers should take care to give it the correct
credentials and call it from the correct context in order to get the results
they need.
You can observe the currently unfortunate consequences of this bug in any non-
global zone that has access to /dev/zvol or any subset of it via sdev profiles.
In particular, a zone used to contain a KVM or similar which has a single zvol
passed through to it using a <device match= block in its zone XML.
Even though sdev makes something of an attempt to control for whether the
caller should have access to nodes in /dev/zvol, it doesn't do this correctly,
or really at all in the lookup call path. So, if we have a zone that's been
given access to any part of /dev/zvol, it can simply look up the full path to
any other zvol on the entire system, and the node will appear and be able to be
used.

This change strips out all of the cross-compiler arguments, (-target,
-B, etc), added to ${CC}, etc via ${CROSSENV} in Makefile.inc1, so it
doesn't infect the build and subsequently the test.
Add comments noting why this logic is being added, and why the logic in
r305041 was necessary/what it was trying to achieve.
This is required after recent changes made to the toolchain to always
specify --sysroot, -target, -B, etc with clang in buildworld (presumably
