wrap some libc functions that do system calls (terminal output) wrap read/write with syscall guard define real_read/write (next dynamic linker find for read/write) guard system calls in remaining code introduce native_internhal.h throw out some debug statements that break things clean up includes a bit declare board_init in native_internhal.h add -ldl to LINKFLAGS for cpu/syscalls

* Native CPU rtc.h implementation
|
|
*
|
|
* The native rtc implementation uses POSIX system calls to simulate a
|
|
* real-time clock.
|
|
*
|
|
* Setting the clock will be implemented using a delta variable.
