The output (if necessary) is placed after NATIVE_COMP feature is
mentioned, ex:

====================

Configured using:
 'configure --without-x --with-native-compilation'

Configured features:
DBUS GMP GNUTLS LIBSELINUX MODULES NATIVE_COMP NOTIFY INOTIFY PDUMPER
SECCOMP SOUND THREADS XIM ZLIB

NATIVE_COMP present but libgccjit not available

Important settings:
  value of $LANG: en_US.UTF-8
  locale-coding-system: utf-8-unix

====================

Not sure if we like to place it elsewhere and/or if we have a better
message to be displayed.

Thanks
