ARM Target dependency

[Trass3r]

With -DLLVM_TARGETS_TO_BUILD=X86 I get the following error, might be good to make the build more modular:

MachineFunctionRaiser.cpp.obj : error LNK2019: unresolved external symbol InitializeARMMachineInstructionRaiser referenced in function "private: void __cdecl MachineFunctionRaiser::init(unsigned __int64,unsigned __int64)" (?init@MachineFunctionRaiser@@AEAAX_K0@Z)

In its present form, the tool depends on LLVM builds of both X86 and ARM.

[Trass3r]

Hence the suggestion to make it more modular or at least check the targets variable during cmake configuration.

Reopening to track addition of support for modular build of llvm-mctoll.

We are working on this now and expect to push a change soon.

Fixed. Commit f4b690b
