LDFLAGS

    Extra flags to give to compilers when they are supposed to invoke the
linker, ‘ld’, such as -L. 

[...]

 LFLAGS

    Extra flags to give to Lex.


However, mkoctfile includes the LDFLAGS into LFLAGS instead


$ mkoctfile -p LFLAGS
-L/home/carandraug/.local/lib/octave/4.1.0+ -L/home/carandraug/.local/lib
$ mkoctfile -p LDFLAGS



This is bug is also present in Octave 4.0.1 (and possibly in previous
versions)


$ /usr/local/bin/mkoctfile -p LFLAGS
-L/usr/local/lib/octave/4.0.1 -L/usr/local/lib
$ /usr/local/bin/mkoctfile -p LDFLAGS



and so there's backwards compatibility implications about fixing this. But
since mkoctifle does not handle lex, it would be possible to keep using
LDFLAGS incorrectly for a few versions, before removing LFLAGS completely.
