the state of amd64 ports on -CURRENT as of 20200827

[Mark Linimon]

The latest build of amd64-CURRENT ports has just completed:

  http://beefy18.nyi.freebsd.org/build.html?mastername=head-amd64-default&build=p546132_s364744

The number of build failures is now 740.  This is an slight drop from
the initial post-clang11 commit of 830.  This is due to diligent work
by a more than a dozen ports committers.  I appreciate their efforts.

For comparison, the last build of amd64-CURRENT before the clang11
import was:

  http://beefy18.nyi.freebsd.org/build.html?mastername=head-amd64-default&build=p544905_s364239

in which there were 66 build failures.

I have added two new analyses to the script that generated the Reason
column in poudriere (technically: processonelog.sh): "duplicate_symbol"
and "clang11".  This new change is not yet deployed on the ports build
cluster.  (I am currently working to make that happen.)

For any ports committer interested in working on fixing these regressions,
the following files may give some hints.
