The meson find_library() function can sometimes return incompatible
libraries which are unsuitable for linking. For example, after
installing the native x86 pqos library on my system, arm64 builds
started trying (and failing) to build the l2fwd-cat example app. Fix
this incorrect detection in our build files by checking that the found
pqos library can actually be used to link apps.
