# Cross compile an llvm-mingw toolchain for windows.
#
# This needs to be built with --build-arg BASE=<image>, where image is the name
# of a docker image that contains a working llvm-mingw cross compiler
# from a similar enough version.
#
# This builds LLVM and all other build tools that need to run on the target
# platform, but just copies over the runtime libraries from the existing
# toolchain in the base docker image.
