Refactor determinePlatform, determineArchitecture, and determineCompiler from dub.platform into strings that can be pasted into generatePlatformProbeFile and remove unused imports.

use GDC's -S flag to avoid creating an object file

Merge pull request #380 from Geod24/ct-platform-probe ...

Make the platform probe the file at CT, hence allow it to work for cross-compilation.

Make the platform probe the file at CT, hence allow it to work for X compilation

Invoke the binary for linking, not the name

Implement separate linking on gdc

Fix output flags for compilers != dmd
