Details: - Added 'skx' and 'knl' sub-configurations to the 'x86_64' configuration family in the config_registry file. - Added logic to configure that avoids committing certain sub-configs to the configuration/kernel registries if those sub-configs cannot be handled properly by the chosen compiler. (This was modeled after similar logic in TBLIS's configure; thanks to Devin Matthews for pointing this out.) First, the compiler and its version are inspected and, based on the results, certain configurations are added to a "blacklist". Then, as the configuration registries are being created, configurations and/or kernels that match items in the blacklist are skipped over and not commited to the registries. Under certain circumstances, omitting a blacklisted configuration will indirectly invalidate other configurations due to the loss of availability of the original blacklisted configuration's kernel set. This additional indirect blacklist is also accounted for. - Added output to the beginning of configure that echos information about the chosen compiler as well as the configurations that are blacklisted and must be stripped from the registries. - Various other cleanups in configure, especially with respect to explicitly declaring local variables in functions. - Comment updates to config/zen/make_defs.mk regarding choice of -march flags based on compiler version.
