stand: Remove i386-only support fire firewire

Remove support for booting off of firewire, and for having dcons via
firewire in the loader. Kernel support for these things is unchanged.
Discussed on arch@ and the current state is not working (and the build
was wrong to boot).

Link stand/i386 components using a linker script

LLD 10.0.0 changed the behavior of the -Ttext option, so that using
-Ttext=0x0 now causes linking of the loaders to fail with:

ld: error: output file too large: 18446744073707016908 bytes

I reported this in https://bugs.llvm.org/show_bug.cgi?id=44715, and
initially reverted the upstream change in r357259 to work around it.

However, after some discussion with Fangrui Song in the upstream ticket,
I think we can classify this as an unfortunate interaction between using
-Ttext=0 in combination with --no-rosegment. (We added the latter
in r332090, because btxld does not correctly handle input with more
than 2 PT_LOAD segments.)

Fangrui suggested to use a linker script instead, and Warner was already
attempting this in r305353, but had to revert it due to "crypto-using
boot problems" (not sure what those were :).

This review updates the stand/i386/boot.ldscript to handle more
sections, inserts some symbols like _edata and such that we use in
libsa, and also discards any .interp section.

It uses ORG which is defined on the linker command line using
--defsym ORG=value to set the start of all the sections.

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.

Disable build-id in i386 binary boot components

A user may enable build-id for all builds by adding
LDFLAGS=-Wl,--build-id=sha1 to /etc/make.conf. In this case the build-id
note ends added up to mbr and pmbr's .text, which makes it too large (it
ends up being 532 bytes). To avoid this explicitly turn off build-id for
these components.

Add support for linker-type-specific flags

r332090 added a LINKER_TYPE test to add the --no-rosegment flag when
linking the i386 loader components with lld. Instead, introduce a
general mechanism for setting LDFLAGS for a specific linker type,
and use it for --no-rosegment.
