PIE/PIC support on base

[David Carlier]

Hi all,

HardenedBSD plans to add PIE support on base in various place.

These are B. Drewery suggestions :

The _pic ones are not needed. The main lib file just needs
INSTALL_PIC_ARCHIVE=yes.

Modifying CFLAGS in every Makefile is not right, just add a USE_PIE or
something to pull in common logic from share/mk.

Also I know that, at least for a start, it wished to be applied in some few
places, like tcpdump/traceroute, sendmail ... shells ... I thought about
also casper/capsicum ... ntp ... jail


Kind regards.
