The following error happens:

In file included from vstate_exec_nolibc.c:2: /usr/include/riscv64-linux-gnu/sys/prctl.h:42:12: error: conflicting types for ‘prctl’; h ave ‘int(int, ...)’ 42 | extern int prctl (int __option, ...) __THROW; | ^~~~~ In file included from ./../../../../include/nolibc/nolibc.h:99, from <command-line>: ./../../../../include/nolibc/sys.h:892:5: note: previous definition of ‘prctl’ with type ‘int(int, long unsigned int, long unsigned int, long unsigned int, long unsigned int) ’ 892 | int prctl(int option, unsigned long arg2, unsigned long arg3, | ^~~~~

Fix this by not including <sys/prctl.h>, which is not needed here since prctl syscall is directly called using its number.
