Even accepting the fact that 'void *' is a valid implementation for va_args,
surely the code generation is wrong in my original bug report for:
'log("Location of i: %p", &i)' as the '...' version should be selected in the
generated code?

'bl      _Z3logPKcz' is generated on ARM, and 'jal     _Z3logPKcPv' is
generated on MIPS.

Surely this is independent of the internal implementation of 'va_args' as we're
not actually calling that function. Commenting out the va_list
forward-declaration results in the correct code being generated.
