using objdump.exe to automatically detect the runtime dll to use for the chosen interpreter
added comment
fix: if interpreter has no runtime, check link library for runtime used.
fix; no longer check link lib when interpreter has no runtime specified, but list all dll's interpreter depends upon and check those for the runtime (1 level deep only)
