    rts: don't define RTS_USER_SIGNALS when signal.h is not present · 4d36a1d3
    Cheng Shao authored and Marge Bot's avatar Marge Bot committed 
    In the rts, we have a RTS_USER_SIGNALS macro, and most signal-related
logic is guarded with RTS_USER_SIGNALS. This patch extends the range
of code guarded with RTS_USER_SIGNALS, and define RTS_USER_SIGNALS iff
signal.h is actually detected by autoconf. This is required for
wasm32-wasi to work, which lacks signals.
