[Buildroot] [for-next 2/3] package/gcc: switch to gcc 6.x as the default

[Romain Naour <romain.naour@gmail.com>]

Even if gcc 5 is still maintained for some time (gcc 5.5 is pending),
switch to gcc 6.x since it has been released since 2016-04-27 and
gcc 7.x is available since 2017-05-02.

We have been having toolchains in the autobuilders with gcc
6.x for a while, so the vast majority of the problems should have
already been solved.
