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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
