A lot more to NTpsec than jsut ntpd.

I've been doing just that for the last 3 days. For good examples
look into Yocto.

Well, we discussed this at length last week. A lot of build systems
do NOT install directly into the system directories. They install
into temporaty directories (trampolines, bounce directories, etc.).
Then they validate the contents of the install directory before
installing the files into the system, into a tarball, or into
something else like a .binpkg.
Gentoo, and Yocto work that way. I think that is also how devs
build apt packages.

Sure, that is what --prefix and --sysprefix are for, as well as
some other parameters.

Not for cross compiles. For native compiles, it depends.
