Welcome to one of the bugs in the linux part of the ports collection...

You said you branded *all* libs, but libtermcap is still unbranded... is
there anything obvious which I overlooked?

In an ideal Ports Collection, every ELF object which is supposed to be a
linux object, is branded as such.
A static linux binary has to be branded, else you will shoot yourself in the
foot (it may cause the system to reboot or do other things you don't want to
happen). A shared linux ELF object may work as intended, but if you want to
do it properly, you have to brand them. I vote for doing it properly.
The "find ... brandelf" line is from the linux_base-8 port, althought I only
brand files in /{,usr/}{,s}bin there... obviously it needs to be extended
(not only in the linux_base-8 port). Patches are welcome.
Bye,
Alexander.
