macOS Linux divergence on formating nan

[JustinMeimar]

          I tried running the current Gazprea Solution on my mac. Initially, I got a lot of errors. The following tester patch fixes most of the errors:

diff --git a/src/toolchain/Command.cpp b/src/toolchain/Command.cpp
index e6cfc2a..7e12686 100644
--- a/src/toolchain/Command.cpp
+++ b/src/toolchain/Command.cpp

   if (pos != std::string::npos) {
     result = result.substr(0, pos);
   }
+  pos = result.find(".dylib");
+  if (pos != std::string::npos) {
+    result = result.substr(0, pos);
+  }
   return result;
 }

When I ran the tests with the patched tester I saw 1 error:
