-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
