Disable force_align_arg_pointer function attribute with MinGW-w64

Browse Source 
The force_align_arg_pointer function attribute is not necessary for
MinGW-w64 to align stack for SSE and generates a compiler warning as
it is ignored. Do not use force_align_arg_pointer with MinGW-w64 to
silence the warning.
