// TestMain allows this test binary to run as a -toolexec wrapper for
// the 'go' command. If LINK_TEST_TOOLEXEC is set, TestMain runs the
// binary as if it were cmd/link, and otherwise runs the requested
// tool as a subprocess.
//
// This allows the test to verify the behavior of the current contents of the
// cmd/link package even if the installed cmd/link binary is stale.
