When compiling the Blackfin kernel, checksyscalls.pl will report lots of missing syscalls warnings. This patch will add some missing syscalls which make sense on Blackfin arch.
Also add ignored syscall list to kill remaining warnings. After appling this patch, toolchain should be rebuilt. Then recompiling the kernel with the new toolchain.
