---------------------------------+------------------------------------------
 Unregisterised builds are currently broken: Compiling C calls in CMM files
 fails with e.g.
 {{{
 error: ‘debugBelch’ undeclared
 }}}

 The C call is being translated into
 {{{
 _cH = (W_)&debugBelch;
 _cG = (W_)&stg_ap_0_ret_str;
 ((void (*)(void *))_cH)((void *)_cG);;
 }}}
 so `pprForeignCall` isn't getting called, and thus doesn't add the
 prototype for `debugBelch`.
