I am trying to build Thrift.
I've cloned Thrift source from git repository.
When I look into `config.log` generated after `./configure`
It is complaining about `yywrap'
The important part is:
configure:16225: checking for bison
configure:16241: found /usr/bin/bison
configure:16253: result: yes
configure:16272: checking for bison version >= 2.5

I've google up for this problem,
and I found that it is flex-related compile issue
and that it can be solved by giving `-lfl` option to `gcc`
But, as I have little knowledge about compiling, make and makefile,
I have no idea in which file and in which line I should put `-lfl`, `
configure.ac`, `Makefile`.
Is there anyone who can give me a tiny hint of it?
For detail information, I am using Ubuntu 14.04 (kernel 3.13.0-55-generic),
Flex 2.5.39.

Jeon.
