MCC fails on unused toolboxes

I am trying to mcc compile a neuroimaging toolbox ("SPM12") into a standalone version.

The process fails with:

No licenses available for toolbox file 'toolbox/fixedpoint/fixedpoint/fi.m'. Compilation terminated.

We indeed do not have the Fixedpoint Toolbox, also we never used it. SPM also should not use/need it.

[fList, plist] = matlab.codetools.requiredFilesAndProducts('spm_make_standalone.m') %spm_make_standalone.m is the wrapper for the actual building

reveils:

#1 'MATLAB' '9.5' 1 true

#2 'Signal Processing Toolbox' '8.1' 8 true

#3 'Image Processing Toolbox' '10.3' 17 true

#4 'Statistics and Machine Learning Toolbox' '11.4' 19 true

#5 'Parallel Computing Toolbox' '6.13' 80 false

#6 'MATLAB Distributed Computing Server' '6.13' 94 false

#7 'Fixed-Point Designer' '6.2' 91 false

#8 'MATLAB Coder' '4.1' 135 false

#9 'Simulink' '9.2' 2 false

It seems that Matlab is not certain (column "certain" = false) with items 5-9. I also do not expect these toolboxes from the requirements of SPM. It may be called in some optional toolbox / code, but it is difficult to be certain.

Licenses are availble for the "core" toolboxes 1-4, but not for items 5-9

How can I request mcc to skip these likely unneeded toolboxes? I am happy with the code failing at execution with these unneeded toolboxes.

Or is it possible somehow to find out WHICH of the >1000 scripts actually use the offending toolboxes so that I could exclude these?
