XCode 15 (on Ventura and Sonoma) has a linker issue, see https://github.com/mesonbuild/meson/issues/12282, workaround is to use ld_classic

For consistency with other such classes, since it represents the homotopy_setup
block.

Also enforce the path to x86-64 GCC.

Options for Bayesian IRF Matching in method_of_moments command

Instead of crashing the preprocessor (because DataTree::DivisionByZeroException
is not caught), just abort the normalization and mark it as failed.

Ref. #92

Those models do not have as many variables as equations, and this case is not
supported by bytecode.

The present commit is an improvement over commit
a8ea57dd, which had already removed bytecode
for the planner objective model.

“clearvars” has been implemented in Octave since version 5.

The preprocessor would try to write bytecode for the planner objective. But
bytecode only works when there are as many endogenous as equations, which is
not the case for the PlannerObjective object derived from StaticModel.
