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.

When building checkpolicy/test, the linker reports the following error:
cc dispol.o -lfl /usr/src/selinux/DESTDIR/usr/lib/libsepol.a
-L/usr/src/selinux/DESTDIR/usr/lib -o dispol
/usr/lib/gcc/x86_64-pc-linux-gnu/6.2.1/../../../../lib/libfl.so:
undefined reference to `yylex'
collect2: error: ld returned 1 exit status
According to flex documentation
(https://github.com/westes/flex/blob/master/doc/flex.texi), -lfl is used
to provide an implementation for yywrap(). However every flex file now
uses "%option noyywrap", which makes -lfl no longer mandatory. Remove
this option from checkpolicy Makefiles.
