This is currently an opt-in build flag. Once ASLR support is ready and stable
it should changed to opt-out and be enabled by default along with ASLR.
Each application Makefile uses opt-out to ensure that ASLR will be enabled by
default in new directories when the system is compiled with PIE/ASLR. [2]
Mark known build failures as NO_PIE for now.
The only known runtime failure was rtld.

and finish the job. ncurses is now the only Makefile in the tree that
uses it since it wasn't a simple mechanical change, and will be
addressed in a future commit.
This is the second part of the commit (the third -- link in usr.sbin/Makefile)
will be done after a more complete review by phk & obrien.
NOTE: the number of drivers included in the default configuration is very
minimal, mainly local clocks and the one I use RAWDCF. Anyone wanting to
have a more complete version will find recompilation very easy.
It builds and runs on both alpha & i386. It also does survive "make world".
