+Notes:
+
+  - the existing test/check for static build in meson.build does not
+    catch this case because e.g. the buildroot toolchain
+    br-arm-full-static-2019.05.1 provides an empty libdl.a
+
+  169 # Among others FreeBSD does not have a separate dl library.
+  170 if not cc.has_function('dlsym')
+  171   dep_dl = cc.find_library('dl', required : with_nouveau)
+  172 else
+  173   dep_dl = []
+  174 endif
