// When using cgo, call the C library for sigaction, so that we call into
// any sanitizer interceptors. This supports using the sanitizers
// with Go programs. The thread and memory sanitizers only apply to
// C/C++ code; this permits that code to see the Go runtime's existing signal
// handlers when registering new signal handlers for the process.
