buildworld/installworld troubling residual v9 > v10

[Jeffrey Bouquet]

For the first time, I had to installkernel AND installworld from sh...
libldns and libucl both wanted to put .so symlinks somewhere.  Fixed
one with a WITHOUT_LDNS... the other proceeded from sh not from
another shell.

edited out the "wrong time " 
.error
in the Makefile, but that should not be relevant...

#tty results in  (many other commands, slew of messages during
port builds obscuring the process, etc...) 

<jemalloc>: Conf string ends with key   # repeated sometimes none,
most of the time one, in port builds many.
