Add WITH_PIE knob to build Position Independent Executables
MFC r344179: 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.
MFC r344181: Fix Makefile conditional after r344179
MFC r344182: Use make's :tl instead of checking "no" and "NO"
MFC r344189: Fixup bsd.prog.mk after r344182
MFC r344211: wlandebug: disable PIE to fix build failure
libifconfig is built as a static-only PRIVATELIB (and there is no _pie.a
version) so disable PIE in libifconfig's consumer.
r345489: Fix GNU objdump build under WITH_PIE
Explicitly specified bare .a libraries need ${PIE_SUFFIX}.
r345490: Apply WITH_PIE changes to other binutils components
Followon to r345489, explicitly specified bare .a libraries need
${PIE_SUFFIX} (although these still built).
r345778: Fix gdb/kgdb build under WITH_PIE
Explicitly specified bare .a libraries need ${PIE_SUFFIX}.
