+Subject: [PATCH] configure.ac: fix static build with idn2 and unistring
+
+Commit 78db40f25c6479b14da5a73adf7207bfbec5ccc5 did not fix static build
+failure
+
+AC_SEARCH_LIBS prepends the library to LIBS as a result -lunistring is
+added before -lidn2. To fix static build, we must set -lunistring after
+-lidn2
