PR/6356: Hubert Feyer: Linux emulation has problem w/ pipes

On linux we don't have syscalls that use retval[1] (edx). So don't
corrupt edx, because the compiler assumes that it has the same
value as before the syscall. Also, compute if we are running under
linux emulation in one place.  XXX: Someday we should have a syscall
function per emulation and avoid the mess.
