[Buildroot] [PATCH 1/2] Revert "package/log4cxx: select boost chrono and date-time with gcc < 7"

[Yann E. MORIN]

Fabrice, All,

(typing this without light, I accidentally broke the bulb... Hopefully,
there will be less typoes than in my usual mails, as I am extra careful
what key I am typing. Hey, that's not even guaranteed! ;-] )

Aj, OK, so the order indeed does not matter much. But semantically, it
does matter, and that the revert comes first is then correct, with your
explanations.

Hihihi! :-)
