## Platform parameters
##
## The "build" "host" "target" terminology below comes from GNU Autotools. See
## its documentation for more information on what those words mean. Note that
## each should always be defined, even when not cross compiling.
##
## For purposes of bootstrapping, think of each stage as a "sliding window"
## over a list of platforms. Specifically, the host platform of the previous
## stage becomes the build platform of the current one, and likewise the
## target platform of the previous stage becomes the host platform of the
## current one.
##
, # The platform on which packages are built. Consists of `system`, a
# string (e.g.,`i686-linux') identifying the most import attributes of the
# build platform, and `platform` a set of other details.
buildPlatform
, # The platform on which packages run.
hostPlatform
, # The platform which build tools (especially compilers) build for in this stage,
