remove i386 support for legacy struct __va_list

commit ffaaa6d230512f3a7f3d040b943517728f3dc3cf removed the
corresponding stdarg.h support for compilers without va_list builtins,
but failed to remove the alternate type definition, leaving incorrect
va_list definitions in place with compilers that don't define __GNUC__
with a value >= 3.
