Compile dnsmasq with TFTP (HAVE_TFTP) support

[Vangelis Tasoulas]

Go to Advanced -> DHCP/DNS and in the Dnsmasq Custom configuration add the enable-tftp option. Save the configuration.
Dnsmasq fails to start with the following error:

Jan  1 01:10:16 ntomata user.debug init[1]: dnsmasq terminated unexpectedly, restarting.
Jan  1 01:10:16 ntomata daemon.crit dnsmasq[2890]: TFTP server not available: set HAVE_TFTP in src/config.h
Jan  1 01:10:16 ntomata daemon.crit dnsmasq[2890]: FAILED to start up

I just moved to FreshTomato from an old version of TomatoShibby where this feature used to work and I used it to setup a PXE server (https://github.com/cyberang3l/how-to-install-pxe-server-on-tomato).

Thank you for the great work!

I noticed that I filed this bug in freshtomato-arm repo. This had to go in the freshtomat-mips. The bug/enhancement might still be valid for freshtomato-arm, but I haven't tested so I close this ticket. I re-opened the same ticket here: https://bitbucket.org/pedro311/freshtomato-mips/issues/21/compile-dnsmasq-with-tftp-have_tftp
