When I broke up the stdio code, the "support pre C99 compilers" va_copy compat

define was no longer visible to vasprintf.  I didn't catch this since I no
longer use such old tools.  Unfortunately, some well-meaning but misguided
individual decided to just cut-and-paste the macro.  :-(
Try to clean up the situation by putting it into a header that can be overriden
by any archs that need to.  If this breaks for anyone (as I said, I no longer
use such old tools and so haven't tested), let me know and I'll fix it.
