Hi Chen,
i presume it is a bit late, but for all other people that are googling for a 
solutions. The problem is in the unistd.h in your include/asm directory. It 
undefines a few contants including __NR_syscall which is called in this file. 
SWI can only take constants, but since __NR_syscall is not defined it takes an 
error or null. remove the undefs from the unistd.h and it should compile.

with regards,
