# Makefile rules for booting from .hc files without a driver.
#
# When booting from .hc files without a compiler installed, we don't have
# the benefit of the GHC driver to add all the magic options required to
# compile the .hc files, so we have to duplicate that functionality here.
# The result is unfortunately ugly, but we don't have another choice.
