[libxml2] Don't overlink executables

[Nick Wellnhofer <nwellnhof src gnome org>]

commit 7016b0e0999156cd1ad96029763351cb6391988b
Author: Nick Wellnhofer <wellnhofer aevum de>
Date:   Sun Apr 3 01:42:17 2022 +0200

    Don't overlink executables
    
    With very few exceptions, utilities and test programs don't require any
    external libraries.
    
    - xmllint and xmlcatalog need libreadline
    - runtest and testThreads need pthreads
