Remove 41 ports that don't build.

The following parts don't build on either i386 or x86-64, and a quick
inspection of their log files don't reveal a potentially simple fix.
In most cases it is not known exactly how this passed before or what
changed to make them fail, but they've been failed a while.  They'll
be imported again once they start passing.
