With the new version, documentation is not generated part of the main
build. This removes the need to alter the Makefile to remove the invoke
on the `chrony.txt` target. Cleanup also explicitly disabling seccomp
(since its experimental) and tomcrypt (Buildroot does not have
libtomcrypt at this time).
