New directory. Contains some kernel code to implement a new system call

1998-06-13  Martin Baulig  <martin@home-of-linux.org>

	* kernel: New directory. Contains some kernel code to
	implement a new system call table () to fetch information
	directly from the Linux kernel.

	* sysdeps/kernel: New directory. Uses the table () function
	from the `kernel' directory to fetch things directly from
	the Linux kernel.

	* sysdeps/Makefile.am (DIST_SUBDIRS): Added `kernel'.

	* configure.in: Removed `build_CC' again.
