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.

when building packages (e.g. for openSUSE Linux)
(random) filesystem order of input files
influences ordering of functions in the output,
thus without the patch, builds (in disposable VMs) would usually differ.
See https://reproducible-builds.org/ for why this matters.
fcb5d5c removed ../include from CFLAGS from libsepol/utils/Makefile so
that a build tool can't find sepol/sepol.h when only libsepol is built
and a system is without sepol.h in standard paths. It should use its own
sepol.h file during build. `oveeride` needs to be used in order not to
be overridden by values provided on a command line. Same problem applies
to LDFLAGS.
Fixes:
$ make CFLAGS="" LDFLAGS=""
make[1]: Entering directory '/root/selinux/libsepol/utils'
cc chkcon.c -lsepol -o chkcon
chkcon.c:1:25: fatal error: sepol/sepol.h: No such file or directory
#include <sepol/sepol.h>
$ make CFLAGS="" LDFLAGS=""
...
make -C utils
make[1]: Entering directory '/root/selinux/libsepol/utils'
cc -I../include chkcon.c -lsepol -o chkcon
/usr/bin/ld: cannot find -lsepol
collect2: error: ld returned 1 exit status

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)
