[Ohrrpgce] Linux 64 bit night build failing

[Ralph Versteegen]

This compile failure finally happened to me too. Looking through the
emitted C code I realised that not only is __builtin_va_list* wrong,
but __builtin_va_list**
is also nonsense which happened to compile to the correct assembly. After
some difficulty I produced a testcase and filed it:
https://sourceforge.net/p/fbc/bugs/951/

The C code that fbc emits is random, but I've only seen 3 different
possibilities. Two compile alright and the third produces that error
message, so we can just ignore the problem and recompile when it fails.
