--jit outputs error when script changes $TMPDIR
Description
Shibata-san reported the following output when running bundler's test with --jit (it looks implicitly passed).

The cause is that bundler's test is modifying $TMPDIR and gcc (or probably clang in the above example) is affected by it.
We should call execvpe with TMPDIR=/tmp (and PATH=xxx for cc1, etc.) instead of execvp to start compiler process. I'm not sure about what other environment variables are needed when we spawn the compiler process.
