## doubts regarding the right conditional or if there is one, simply redefine
## in that platform's .mk in this directory.  I'll keep a close eye on this to

## The main makefile and/or this file requires that OS_ARCH be set
## to something to describe which chip that this OS is running on.
## This can be used to change which tools are used and/or which
## compiler/loader options are used.  It will probably also be used
## in constructing the name object file destination directory.
