I'm not sure what the default triple represents, but there seems to be
four cases;

1) OS architecture is 32-bit, target is 32-bit -- use VC\bin
2) OS architecture is 64-bit, target is 32-bit -- use VC\bin
(Virtualization should allow the 32-bit linker to run and generate
32-bit code)
3) OS architecture is 32-bit, target is 64-bit -- use VC\bin\x86_amd64
4) OS architecture is 64-bit, target is 64-bit -- use VC\bin\amd64

Your if-chain looks right to me, if getDefaultTargetTriple() returns
architecture information that matches the OS.

It should work, though, thanks to 32-bit virtualization, right?
