After libsepol is modified (for example while developing new features or
fixing bugs), running "make install" in the top-level directory does not
update the programs which use libsepol.a. Add this static library to the
target dependencies in order to force their updates. This makes "make"
use libsepol.a in the linking command without using LDLIBS.
While at it, copy what commit 14d7064348 ("libselinux: Allow
overriding libsepol.a location during build") introduced in libselinux
Makefile by using a new LIBSEPOLA variable in all Makefiles.

- Sort included header files by their number of path components then
alphabetically.
- Include unistd.h and sys/types.h only once.
- Include sys/uio.h to get readv() and writev() declarations when
compiling with musl libc.
- Include poll.h instead of sys/poll.h as building with musl results in
the following message:
/usr/lib/musl/include/sys/poll.h:1:2: error: #warning redirecting
incorrect #include <sys/poll.h> to <poll.h> [-Werror=cpp]
#warning redirecting incorrect #include <sys/poll.h> to <poll.h>

When running "make all" in the root directory on a system where SELinux
is not installed and where $DESTDIR targets a directory where the
libraries have been installed, the build fails in mcstrans/utils with
the following error:
transcon.c:7:10: fatal error: 'selinux/selinux.h' file not found
and then:
/usr/bin/ld: cannot find -lselinux
Fix this by adding -I$(PREFIX)/include to CFLAGS and -L$(LIBDIR) to
LDLIBS like other subdirectories do.
While at it, remove the useless -L../src parameter.

When running "make install" in the root directory of the project, with
variable DESTDIR set and while being on a system without SELinux, the
compiler complains while building:
fatal error: selinux/selinux.h: No such file or directory
Other subdirectories add -I$(PREFIX)/include to CFLAGS and -L$(LIBDIR)
to the linking command line, in order to find libselinux headers and .so
file. Do this too in mcstrans.
While at it, mcstrans Makefile uses -I../include but this directory does
not exist. Remove this option.

All the other makefiles just have LIBDIR optionally set so it can be
overridden. These makefiles were autodetecting incorrectly. uname -i
returns "GenuineIntel" so should have been uname -m.
