Rather than linking in the libraries explicitly, can you have the build do
a "ninja install" at the end to place the libraries and drivers in their
correct paths. That should mean that the test app (via eal) auto-loads all
drivers from EAL_PMD_PATH (/usr/local/...). It would save having to make
further changes to this file to link in any additional drivers.

EAL_PMD_PATH is based off of $prefix for the build or install, so you can
adjust that using meson options, if putting the drivers in /usr/local is
not desirable for your test environments.
