HEAD doesn't build. Totally stalled.

[Moritz Angermann]

For some reason, you end up in the defined RTS_SSP_SYMBOLS, I believe and
then the RTS wants __stack_chk symbols. Which it can’t find when linking.

Replacing

#if !defined(mingw32_HOST_OS) && !defined(DYNAMIC)
#define RTS_SSP_SYMBOLS                                \
      SymI_NeedsProto(__stack_chk_guard)               \
      SymI_NeedsProto(__stack_chk_fail)
#else
#define RTS_SSP_SYMBOLS
#endif

With just


#define RTS_SSP_SYMBOLS


Should do. I hope.

Currently only on mobile phone :-/

Cheers,
 Moritz
