Review Comment:
   signal() is built only with CONFIG_ENABLE_ALL_SIGNALS 
(libs/libc/signal/Make.defs, sig_signal.c). With CONFIG_ENABLE_PARTIAL_SIGNALS 
(the default with DEFAULT_SMALL) or CONFIG_DISABLE_ALL_SIGNALS, 
set_sigint_handler() does not link.
   
   Fix: add -DDUK_CMDLINE_SIGNAL only when CONFIG_ENABLE_ALL_SIGNALS=y.
