This is precisely what I wanted to known before to replying.

I extracted all (or nearly all) packages existing in Buildroot. I found 269 
packages that use libool:

$ grep -ho 'VERSION="[0-9.]*' */ltmain.sh  | sort | uniq -c | sort -n
      1 VERSION="1.5.24
      1 VERSION="2.2.4
      3 VERSION="1.5.22
      5 VERSION="1.5.26
     13 VERSION="2.2.6
     29 VERSION="2.4.6
     67 VERSION="2.4.2

There 23 packages that use libtool < 2.4:
  - bellagio
  - celt051
  - dbus-cpp
  - eventlog
  - gtk2-engines
  - lesstif
  - libargtable2
  - libesmtp
  - liblo
  - libmhash
  - libnetfilter_conntrack
  - libnetfilter_log
  - libnfnetlink
  - libpthread-stubs
  - lite
  - log4cxx
  - matchbox-lib
  - metacity
  - sdl_sound
  - sylpheed
  - xapp_xinput-calibrator
  - xdriver_xf86-input-tslib
  - xdriver_xf86-video-imx

4 of them already call autoreconf: bellagio, dbus-cpp, libnetfilter_log, 
libnfnetlink.

I am going to create a configuration with all of these packages.
