Remove FlexLexer.h; rather copy it from /usr/include when flex is run

-// This file defines FlexLexer, an abstract class which specifies the
-// external interface provided to flex C++ lexer objects, and yyFlexLexer,
-// which defines a particular lexer class.
-//
-// If you want to create multiple lexer classes, you use the -P flag
-// to rename each yyFlexLexer to some other xxFlexLexer.  You then
-// include <FlexLexer.h> in your other sources once per lexer class:
-//
-//	#undef yyFlexLexer
-//	#define yyFlexLexer xxFlexLexer
-//	#include <FlexLexer.h>
-//
-//	#undef yyFlexLexer
-//	#define yyFlexLexer zzFlexLexer
-//	#include <FlexLexer.h>
