Lib jemalloc building problem

Hey folks,

I'm trying to build the openvswitch on an Ubuntu jammy (22.04.2 LTS) and passing the parameter LIBS=-ljemalloc in configure according to the documentation: https://readthedocs.org/projects/openvswitch/downloads/pdf/stable/ (Release 3.1.1)

I see the build process using this lib but I don't see the linker step applying the shared lib in the binary.

...
test -d _debian || mkdir _debian
cd _debian && ( \
 test -e Makefile || \
 ../configure --prefix=/usr --localstatedir=/var --enable-ssl LIBS=-ljemalloc \
     --sysconfdir=/etc \
...

The binary dependencies are listed below:

 Description: Open vSwitch switch implementations
  Open vSwitch is a production quality, multilayer, software-based,
  Ethernet virtual switch. It is designed to enable massive network
  automation through programmatic extension, while still supporting
  standard management interfaces and protocols (e.g. NetFlow, IPFIX,
  sFlow, SPAN, RSPAN, CLI, LACP, 802.1ag). In addition, it is designed
  to support distribution across multiple physical servers similar to
  VMware's vNetwork distributed vswitch or Cisco's Nexus 1000V.
  .
  openvswitch-switch provides the userspace components and utilities for
  the Open vSwitch kernel-based switch.

I expected to see the link looking at the binary with readelf:

If I build the same code base with an Ubuntu Focal, the link with libjemalloc works fine.
e.g. Ubuntu Focal: 20.04 LTS

Maybe I'm missing something, any idea why I'm not linking?

Kind regards,
