The ModelGenerator is now included in the fwi-params, so that the input
can be generated at runtime.

# FIXME: This is an ugly hack.
# When using _GNU_SOURCE or any other definition used in features.h, we need
# to define them before mcc includes nanos6.h from the command line. So the
# only chance is by setting it at the command line with -D. Using the DEFINES
# below, reaches the command line of the preprocessing stage with gcc.

# We compile the ModelGenerator using gcc *only*, as otherwise it will
# be compiled with nanos6, which requires access to /sys to determine
# hardware capabilities. So it will fail in the nix-build environment,
# as there is no /sys mounted.
# Also, we need to compile it with the builder platform as target, as is going
# to be executed during the build to generate the src/generated_model_params.h
# header.
