[Buildroot] [PATCH 1/1] support/dependencies: require at least CMake 3.8

[Fabrice Fontaine]

gerbera package in version 1.3 unfortunately now requires CMake >= 3.8
for C++17 macros:
https://github.com/gerbera/gerbera/commit/b5fd39f30fb10385ec228b71377685206a609c3a

So we need to bump our requirement from 3.1 to 3.8. If the host doesn't
have a CMake >= 3.8, Buildroot will build its own host-cmake package.

Fixes:

Why do you drop this comment?

So, yes, the last part of it is wrong: we won;t whine, but we will build
our own. Otherwise, the comment is still valid, and I prefer a "generic"
comment rather than the name of the affected package.

If onwe wants to check why the version is set to 3.8, one can git-blame
the file, and see the commit log that identifies the culprit package.

Additionally, now that we update the version to 3.8, you may also remove
package/json-for-modern-cpp/0001-buildsystem-relax-requirement-on-cmake-version.patch

Yann E. MORIN.
