[PATCH] DVB: "errno" undefined

Actually, the problem has its origin in my removal of all in-kernel
syscalls (except execve, which is non-trivial) earlier this year.  This
change was blindly reverted by the maintainer, while at the same time the
local errno variable was removed.  See also
http://linux.bkbits.net:8080/linux-2.5/hist/drivers/media/dvb/frontends/tda=
1004x.c

This patch is the one that was already merged earlier.  I'm now also
removing the definitions for the kernel syscalls on i386 to make it harder
to reintroduce them again.  This was already done for ppc64, the others
should probably follow.
