+fix from upstream to drop ugly filesystem checks that fail horribly when cross-compiling
+
+From c4b7e5f2b287ee3d1de8f706b809a8e217720c4e Mon Sep 17 00:00:00 2001

+Subject: [PATCH] Simplify the detection of OpenSSL libcrypto by using
+ standard autoconf macros rather than a local copy of
+ AC_LBL_SSLEAY.
+
+AC_LBL_SSLEAY is old and has not kept pace with some more recent
+developments in packaging like Debian and Ubuntu's multiarch support.
+The autoconf macros have been updated to handle multiarch so using them
+means that tcpdump gains the ability to be built with libcrypto on these
+new multiarch distros and to work successfully with Travis CI, which
+uses Ubuntu 12, which is one such multiarch distro (see GH-32).
+
+Fixes GH-33
