Failure log from ARM build using an external tool chain.

In fact, it's more than arm.

I did an exp-run for tijl@ recently to make ld(1) no longer link implicitely (PR 192062) and esound was broken too:

You may contact tijl@ to know if he has patches already.

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=192062 has a list of ports with missing libraries. I currently have patches up to and including the devel category. I can commit those if it helps.

Please do, most of those are failing for me for exactly the reason specified in the bug link.
