[PATCH] linux: Use long int for syscall return value

[XingLi]

From: Xing Li <lixing@loongson.cn>

The linux syscall ABI returns long, so the generic syscall code for
linux should use long for the return value.

This fixes the truncation of the return value of the syscall function
when that does not fit into an int.
