[PATCH] libnl: fix compilation on hosts without lex

[PATCH] libnl: fix compilation on hosts without lex

[Eric Bénard]

* libnl's makefiles are calling $(LEX) but only define $(FLEX), thus
compilation on a host which doesn't have lex fails with :
| lex --header-file=route/cls/ematch_grammar.h  -o route/cls/ematch_grammar.c route/cls/ematch_grammar.l
| make[1]: lex: Command not found
| make[1]: *** [route/cls/ematch_grammar.c] Error 127

* this patch fix this by setting LEX variable to flex tool

I have prepared a patch for this issue but I did patch the Makefile.am
to use $(FLEX) as this is the fix commited in upstream 3.2.17. If you
do not object, I'd like to propose mine patch for review as it is more
in line with upstream fix.

as the end result is the same, the maintainer now has the choice ;-)
