[Buildroot] Adding Flex library

[Doha Ehab]

Hello,
 I am using buildroot-2017.02.9*. *I have chosen flex library from target
packages -> Development Tools. My question is, am I supposed to find the
flex binary under output-> host ->usr->bin? I checked the Config.in for
flex and the package address is incorrect (http://flex.sourceforge.net/)

"Target packages" are target packages, so they are cross-compiled and
installed in the target filesystem, i.e output/target, and are
therefore present in the filesystem images generated in output/images.

If you need the host variant of flex (i.e built with the native
compiler) then your package should have a dependency on host-flex.
There is no option in menuconfig to enable host-flex, because it is
generally just a build dependency of another package.

Best regards,

Thomas
