There's nothing interesting to look at, it's just a "normal" build of
a C program.  The compiler echoes its command lines to compile each
file, then the linker its link command line, then you see the list of
preloaded Lisp files.  That's it.

Since Emacs currently doesn't support any kind of FFI, this is hardly
a tutorial-level stuff.  And even if/when we do have FFI, adding a
library through it will require good knowledge of how Emacs represents
data types internally, so that must be mastered first.

Anyway, historically, the best person to add documentation of such
kind is someone who is interested in it.  Consider this an invitation
to start such a tutorial.  TIA.
