audit: new package

[Thomas:
 - remove S01audit, which isn't completely compliant with the
   Buildroot style.
 - make the package available only on architectures for which the
   system call tables are available, and add some comments about this
   in the .mk file.]

+Subject: [PATCH] Do not call posix_fallocate() if unavailable
+
+uClibc does not implement posix_fallocate(), and posix_fallocate() is
+mostly only an hint to the kernel that we will need such or such
+amount of space inside a file. Adding a check around the
+posix_fallocate() call so it is only called when it is available.
