Log:
THRIFT-865. Make Thrift buildable without libfl

yywrap is only needed if we need one lexer context to traverse multiple
input files.  This feature isn't used by Thrift, so we disable it with
"option noyywrap".  With yywrap disabled, there is no need to link to
libfl if flex is the lex implementation used.

With this patch, release tarballs can be built without lex.
