Git on Windows provides bash

With non-GNU tar, passing the --sort option may print out an
error message saying the option isn't supported; that's
confusing and not useful to the consumer.

This will prevent the macro definition of min and max which breaks
the use of std::min and std::max

Also add trigger to switch to KDE_COMPILERSETTINGS_LEVEL of latest
KDECompilerSettings on ECM dependency in KF modules to 5.85

MO_CHANGELOG

Existing projects have muliple calls of find_package(ECM) and
include(KDECompilerSettings), usually in pairs, e.g. for forks of
3rd-party software or examples.

While this is not a recommnended setup, as there is no official
mechanism to properly reset previously created setings, those
existing projects and their releases can be supported by
discarding any auto-level values at the end of the include,
so the next can pick up again the value of any closer
find_package(ECM) call.
