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.
