 # Output will be places in a directory name based on Toolchain and configuration
 # be default this will be "newlib/Debug".  We use a python wrapped MKDIR to
 # proivde a cross platform solution. The use of '|' checks for existance instead
 # of timestamp, since the directory can update when files change.
