+kernel headers have restructured mips syscall generation in kernel

+syscall numbers based on old logic, this patch includes the legacy
+UAPI headers to get these defines

+Fixes errors e.g.
+../../../../git/sysdeps/linux-gnu/mips/trace.c:138:29: error: '__NR_O32_Linux' undeclared (first use in this function)
