Introduce CI_TARGET_TRIPLET and CI_TARGET_ABI. Rename CI_HOST_MACHINE and CI_TARGET_MACHINE, respectively, to CI_HOST_ARCH and CI_TARGET_ARCH, following on the conventional target triplet nomenclature. Introduce CI_BUILD_SYSTEM and CI_BUILD_ARCH, following on the GNU Autotools (host/build/target) practice and nomenclature. Ensure that CI_TARGET_SYSTEM, CI_TARGET_ARCH and CI_TARGET_ABI are all initialized when verifying a cross-platform build. Work around an obscure CMake error by ensuring that CMake variables (CMAKE_AR and CMAKE_RANLIB) are initialized to the full executable paths of their CI_* equivalents (CI_AR and CI_RANLIB). Implement other general-purpose improvements: * Check all CI_NO_* variables in an arithmetic context, to allow setting them explicitly to zero in external configurations. * Label the assertions with descriptions of what's being asserted. * Add more comments and tracing printouts.
