make all test CC=fatcosmocc AR='fatcosmoar rcu' This change introduces a program named mktemper.com which provides more reliable and secure temporary file name generation for scripts. It also makes our ar.com program more permissive in what commands it'll accept. The cosmocc command is improved by this change too.
