The exact set of environment variables required by xt-xcc and xt-clang is a bit of a dark magic and error-prone. TOOLCHAIN_VER is definitely one of them and the error message was puzzling when TOOLCHAIN_VER was undefined or not exported. - Add TOOLCHAIN_VER to the list of variables in the error message - Replace the vague "toolchain not found" in the error message with the more useful "XCC/install/tools//XtensaTools/bin/xt-xcc not found" where the double slash and comparison with the filesystem clearly point at where TOOLCHAIN_VER is missing.
