This reverts commit 3632abd01abb8dfff230e18f828af705da488f97.
Multiple people have expressed issues with flex-2.6.2; personally I had
problems compiling libsepol from meta-selinux (for libselinux). I tried
upgrading to flex-2.6.3, but that caused binutils-cross_2.27 to fail.
The simplest for now is to downgrade to flex-2.6.0.
