How can I define AMD64 as the processor architecture instead of MSIL when compiling a .NET assembly using Matlab Compiler SDK?

When running a compilation as follows, using Matlab 2015a compiler SDK:

mcc -W 'dotnet:EVA,Class1,3.5,H:\Mijn Documenten\MATLAB\TestKey.snk,remote' -T link:lib -d 'H:\Mijn Documenten\MATLAB\EVA\for_testing' -v 'class{Class1:H:\Mijn Documenten\MATLAB\addFive.m}'

a MSIL assembly is generated. Calling these assemblies from PHP seems problematic, although AMD64 assemblies work fine. Is there a way to compile to AMD64 with Matlab Compiler SDK
