start Stroika 2.0a7x
Critical make/configure script fixes - so you can externally say

	make default-configuration DEFAULT_CONFIGURATION_ARGS='--make-define qBuildThirdPartyProducts_OpenSSL=1' apply-configurations

Fixing the support for DEFAULT_CONFIGURATION_ARGS= and really for --make-define was needed so we could build openssl
but not depend on it (since our code depending on openssl doesnt compile yet but we need openssl built for other projects).
Improved checking for installed tools in makefile
Merge branch 'DEV' of github.com:SophistSolutions/Stroika into DEV
v2.0a7: no real testing; just some makefile/build script improvements/fixes
