Environment variable TMPDIR may be already set for the user building
and this could be equal to $XDG_RUNTIME_DIR or /tmp which are existing
directories. Then when running 'make clean', there are unintended side

Add a simple test for secilc -O to make sure that it produces the
expected output. This might produce some false positives when the output
of secilc/checkpolicy changes slightly, in which case the expected CIL
will need to be updated along with the change.
The test should normally work even with a checkpolicy built from an
older tree, as long as it produces the same CIL output, so it uses the
checkpolicy it finds in PATH by default.
The test policy is taken from an e-mail from James Carter:

Policy developers can set a default_range default to glblub and
computed contexts will be the intersection of the ranges of the
source and target contexts. This can be used by MLS userspace
object managers to find the range of clearances that two contexts
have in common. An example usage is computing a transition between
the network context and the context of a user logging into an MLS
application.
For example, one can add a default with
this cil:
(defaultrange db_table glblub)
or in te (base module only):
default_range db_table glblub;
and then test using the compute_create utility:
$ ./compute_create system_u:system_r:kernel_t:s0:c1,c2,c5-s0:c1.c20 system_u:system_r:kernel_t:s0:c0.c20-s0:c0.c36 db_table
system_u:object_r:kernel_t:s0:c1,c2,c5-s0:c1.c20
Some example range transitions are:
User Permitted Range | Network Device Label | Computed Label
---------------------|----------------------|----------------
s0-s1:c0.c12 | s0 | s0
s0-s1:c0.c12 | s0-s1:c0.c1023 | s0-s1:c0.c12

Since Darwin systems do not have GNU sed installed, the Darwin sed is
missing the "regexp-extended" flag needed to modify the secilc markdown
files before processing with pandoc.
A quick fix for Mac users is to `brew install gnu-sed` and to use gsed.

Modify cil_gen_node() to check to see if the cil_db supports multiple
declarations, and if so, to check whether or not the
repeated symbol is eligible to share the existing, already-stored datum. The
only types considered so far are CIL_TYPE and CIL_TYPEATTRIBUTE, both of
which intall empty datums during AST building, so they automatically return
true.
Test: Build policy with multilpe type and attribute declarations, and
without. Policies are binary-identical.

There were several places in the makefiles where LDLIBS or CFLAGS were
supposed to include options to build. They were missing the override
keyword so would be skipped if these vars were set on the make cmdline.
Add the override directive to fix this.

The toolchain automatically handles them and they break cross compiling.
LDFLAGS should also come before object files, some flags (eg,
-Wl,as-needed) can break things if they are in the wrong place)

Added "-G, --expand_generated" option to specify that all automatically
generated attributes should be expanded and removed.
Added "-X, --expand_size <SIZE>" option to specify which attributes
are expanded when building a kernel policy. All attributes that have
less types assigned to it than SIZE will be expanded when writing AV
rules.

The program secil2conf uses the libsepol function
cil_write_policy_conf() to create a policy.conf file from CIL policy.
By default a file called "policy.conf" will be created, but the "-o"
option can be used to write to a different file. The "-M" option can
be used to override the mls statement in CIL. The "-P" option will
cause tunables to be treated as booleans.

When running "make all" several times in the root directory of the
project, the following lines always appear (and the command takes some
seconds to complete on my system with a slow hard drive):
xmlto man secilc.8.xml
Note: Writing secilc.8
This is because "make man" always builds secilc.8 even though
secilc.8.xml has not been modified. Introduce an intermediate target to
avoid this behavior.
