[Buildroot] [PATCH v3 2/2] support/dependencies: set cmake version min to 3.10

[Yann E. MORIN]

James, All,

Maybe, but as my pro alter-ego already pointed out [0], cmake 3.10 and
above require a C++ compiler, which supports the emplace_hint metchod,
which is not always availble on the distributions Buildroot is supposed
to support.

Which means that, by bumping the cmake requirement to 3.10, all cmake
packages will have to depend on BR2_HOST_GCC_AT_LEAST_4_8 (or 4.9 or
what?).

I am not saying we do not want this, but the bump should not be lightly
applied. It has consequences.
