Subject: [PATCH] checkpolicy: remove -lfl from LDLIBSlogin
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.
