+   libgccjit internally generates assembler, and uses "driver" code
+   for converting it to other formats (e.g. shared libraries).
+
+   By default, libgccjit will use an embedded copy of the driver
+   code.
+
+   This option can be used to instead invoke an external driver executable
+   as a subprocess.
