It's not a gcc problem, it seems to be a bug in the klibc open()
function. open() is a problematic function since it's technically
defined as being varadic, and with regparm varadic and non-varadic
functions have calling conventions.
Thus, it's either a klibc or an ash problem, so it's in my court. I'll
take care of it.
