This is fine (except that you may want to stirp the binary) and builds etex
with a static libkpathsea whereas Debian uses a shared library.  Configuring
with --enable-shared yields .libs/etex, and you can build etex against the
installed shared library with --with-system-kpathsea (provided you have the
kpathsea development files).
