Subject: [PATCH 2/2] configure: fix AC_CHECK_FUNCS(TLS_method TLSv1_method
 ...) failure on static linking

If building as static lib, AC_CHECK_FUNCS(TLS_method TLSv1_method ...)
fails due to missing -lz in $LIBS.
At the moment, $LIBS contains "-lssl $LIBCRYPTO" only discarding
previous $LIBS content.

Add $LIBS to:
LIBS="-lssl $LIBCRYPTO"
as:
LIBS="-lssl $LIBCRYPTO $LIBS"
This way $LIBS will contain -lz at the end of linking command that in
static linking build is mandatory.
