I though about that, but currently we don't guarantee a definition for
va_list everywhere libiberty.h is used.  We do so in the gcc directory
which gets stdarg.h via system.h.  But many/most of the files in the
libiberty directory itself don't include stdarg.h/varargs.h to get
va_list, and thus they fails to compile.  Other packages which use
libiberty.h (binutils? gdb?) would have the same issue.

Okay, here's what I did, regarding {v}asprintf in libiberty.h:
