Ed Maste bcf99d2d99 Add WITH_PIE knob to build Position Independent Executables 
Building binaries as PIE allows the executable itself to be loaded at a
random address when ASLR is enabled (not just its shared libraries).

With this change PIE objects have a .pieo extension and INTERNALLIB
libraries libXXX_pie.a.

MK_PIE is disabled for some kerberos5 tools, Clang, and Subversion, as
they explicitly reference .a libraries in their Makefiles.  These can
be addressed on an individual basis later.  MK_PIE is also disabled for
rtld-elf because it is already position-independent using bespoke
Makefile rules.

Currently only dynamically linked binaries will be built as PIE.

This subtree is world-exportable, as it does not contain any
cryptographic code.

At the time of writing, it did not even contain source code, only
Makefiles and headers.

Please maintain this "exportable" status quo.

Thanks!
