cmake is now filled with 'sudo' but with sudo timeout this should be
fine.

Bananymous 8ec6d4c9fc LibC: we don't parse syscall arguments in unistd 
We just call Kernel::syscall() with 5 arguments from the variadic function.

This was a necessary addition since the syscall() function
used over 2 KiB of stack space.

Bananymous adb14ba373 Kernel: Userspace signal handlers are now called one at a time 
I added a syscall for telling the kernel when signal execution has

be confirmed.
