[Lost] [Patch] stdarg.h ersetzen

[Toni Kaufmann <toni@xxxxxxxxxxxxxxxx>]

Dieser Patch ersetzt die bisherige stdarg.h in src/modules/include durch
eine in src/include, da ich diese auch in kernel2 benutzen möchte.
Weiter werden bei der neuen die builtin-Definitionen verwendet. Dies
sorgt zwar dafür, dass es nur noch  mit gcc funktioniert, aber das ist
ja sowieso schon der Fall. Ein weiterer Vorteil dieser Definitionen ist,
dass sie garantiert zur aktuellen Plattform passen, nicht wie die aktuellen.
