+Subject: [PATCH] Do not check for ERR_remove_thread_state() (do not link ssl
+ into every library)
+
+This reverts commit c4e9d9bd662de7f575f2172c160795d452ebe709
+("sample/https-client: check for ERR_remove_thread_state() existence").
+
+Calling AC_SEARCH_LIBS() modifies LIBS - -lcrypto incorrectly
+ends up in LIBS, and thus linked to by libevent_core.so.
+
+Checking for ERR_remove_thread_state should no longer be needed
+because it was introduced in openssl 1.0.0, and the previous line
+0.9.8 had support discontinued at the end of 2015.
+
+Fixes: #473
