* Added clone() system call.
* Proper implementation of bits/syscalls.h, no cheating by just including <asm/unistd.h>. * Proper implementation of syscall.S, it no longer contains the __syscall_error, instead it contains code which makes syscall(nr,...) a system call. * Added sysdep.S which contains the code for __syscall_error. * Added some macros to sysdep.h. * Added sys/procfs.h, which is needed when compiling with thread support. * Removed unused syscall-cris.c.
