Add an -fno-temp-file flag for compilation

Our build system does not handle randomly named files created during
the build well. We'd prefer to write compilation output directly
without creating a temporary file. Function parameters already
existed to control this behavior but were not exposed all the way out
to the command line.

Patch by Zachary Henkel!
