We have commands and variables to show this information already.  See

  M-x emacs-version
  M-: emacs-build-system RET
  M-: system-configuration RET
  M-: system-configuration-features RET
  M-: system-configuration-options RET

See also the command emacs-build-description, which inserts most of
the relevant information into the current buffer.
