- Put parallelization menu first
- Fix the logic for variable definitions in this menu
- change jhalfs to reflect the separation of optimization and
parallelization
- validate new variables
- remove MAKEFLAGS from the validation of optimize variables
- also remove the black list, which has not been used in years.
In order to be able to pass NINJAJOBS=1 when optimize is 0, we
add two paramters to this function. The three parameters are
then:
- the name of the package (tested against opt_override)
- MAKEFLAGS for this package
- NINJAJOBS for this package
