Make build shut up about system() without return value check.
st.c:1321:2: warning: ignoring return value of function declared with warn_unused_result attribute [-Wunused-result]
system(cmd);
^~~~~~ ~~~
Debatable whether an error here should case exit(EXIT_FAILURE). Just
preserving the existing behaviour for now.
