f28c1d0c5c llvm-objcopy: Install llvm-strip, and optionally strip, links
Just as elftoolchain's objcopy doubles as strip, so does LLVM's. This
ensures that a strip binary is still present for WITH_LLVM_BINUTILS
builds. Note that we do not currently have a committed copy of the
manpage generated from the rST source so no manpage is installed for
(llvm-)strip.

021385aba5 Add WITH_LLVM_BINUTILS to install LLVM binutils instead of Elftoolchain
When WITH_LLVM_BINUTILS is set, we will install the LLVM binutils as
ar/ranlib/nm/objcopy/etc. instead of the elftoolchain ones.
Having the LLVM binutils instead of the elftoolchain ones allows us to use
features such as LTO that depend on binutils that understand LLVM IR.
Another benefit will be an improved user-experience when compiling with
AddressSanitizer, since ASAN does not symbolize backtraces correctly if
addr2line is elftoolchain addr2line instead of llvm-symbolizer.
See https://lists.freebsd.org/archives/freebsd-toolchain/2021-July/000062.html
for more details.

This is currently off by default but will be turned on by default at some
point in the near future.

8e1c989abb Don't build and install {llvm,clang,lldb}-tblgen for the target
The tablegen binaries are only needed to build software that uses
LLVM's infrastructure for command line options,
disassembler tables, etc. They are not user-facing binaries and

c8edd05426 clang: Support building with GCC and DEBUG_FILES disabled
If MK_DEBUG_FILES=no then the Clang link rule has clang as .TARGET,
rather than clang.full, causing the implicit ${CFLAGS.${.TARGET:T}} to
be CFLAGS.clang, and thus pull in flags intended for when your compiler
is Clang, not when linking Clang itself. This doesn't matter if your
compiler is in fact Clang, but it breaks using GCC as, for example,
bsd.sys.mk adds -Qunused-arguments to CFLAGS.clang. This is seen when
trying to build a bootstrap toolchain on Linux where GCC is the system
compiler.

Thus, introduce a new internal NO_TARGET_FLAGS variable that is set by
Clang to disable the addition of these implicit flags. This is a bigger
hammer than necessary, as flags for .o files would be safe, but that is
not needed for Clang.

Note that the same problem does not arise for LDFLAGS when building LLD
with BFD, since our build produces a program called ld.lld, not plain
lld (unlike upstream, where ld.lld is a symlink to lld so they can
support multiple different flavours in one binary).

07bab4417d Add WITH_LLVM_CXXFILT option to install llvm-cxxfilt as c++filt
Since elftoolchain's cxxfilt is rather far behind on features, and we
ran into several bugs, add an option to use llvm-cxxfilt as an drop-in
replacement.

It supports the same options as elftoolchain cxxfilt, though it doesn't
have support for old ARM (C++ Annotated Reference Manual, not the CPU)
and GNU v2 manglings. But these are irrelevant in 2020.

Note: as we already compile the required libraries as part of libllvm,
this will not add any significant build time either.

57f804675e remove GCC 4.2.1 build infrastructure
As described in Warner's email message[1] to the FreeBSD-arch mailing
list we have reached GCC 4.2.1's retirement date.  At this time all
supported architectures either use in-tree Clang, or rely on external
toolchain (i.e., a contemporary GCC version from ports).

GCC 4.2.1 was released July 18, 2007 and was imported into FreeBSD later
that year, in r171825.  GCC has served us well, but version 4.2.1 is
obsolete and not used by default on any architecture in FreeBSD.  It
does not support modern C and does not support arm64 or RISC-V.

Thanks to everyone responsible for maintaining, updating, and testing
GCC in the FreeBSD base system over the years.

So long, and thanks for all the fish.

fd9d16bddb Ensure lld respects the WITH/WITHOUT_SHARED_TOOLCHAIN option
Traditionally, toolchain components such as cc, as, and ld have been
built as static executables.  The WITH_SHARED_TOOLCHAIN option from
src.conf(5) is meant to link these as regular executables, e.g. using
shared libraries.

The build of ld.lld did not yet check this option.  Fix the Makefile so
it will do so now.

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.
