This makes it possible to build llvm-symbolizer for Android, which
is one of the prerequisites for running the sanitizer tests on Android.

Nothing pulls them in yet, but they will be needed for check-llvm.
LineEditor depends on libedit, so create a gn/build/lib for it, following the
usual pattern.

Also add build files for deps DebugInfo/Symbolize, ToolDrivers/dll-tool.
Also add gn/build/libs/xar (needed by llvm-objdump).
Also delete an incorrect part of the symlink description in //BUILD.gn (it used
to be true before I made the symlink step write a stamp file; now it's no
longer true).
These are all binaries needed by check-lld that need symlinks.

Version.inc.in processing has a potentially interesting part which I've punted
on for now (LLD_REVISION and LLD_REPOSITORY are set to empty strings for now).
lld now builds in the gn build. But no symlinks to it are created yet, so it
can't be meaningfully run yet.

The comments at the top of
llvm/utils/gn/secondary/llvm/include/llvm/Config/BUILD.gn and
llvm/utils/gn/build/write_cmake_config.py should explain the main bits
happening in this patch. The main parts here are that these headers are
generated at build time, not gn time, and that currently they don't do any
actual feature checks but just hardcode most things based on the current OS,
which seems to work well enough. If this stops being enough, the feature checks
should each be their own action writing the result to somewhere, and the config
write step should depend on those checks (so that they can run in parallel and
as part of the build) -- utils/llvm/gn/README.rst already has some more words
on that in "Philosophy".
(write_cmake_config.py is also going to be used to write clang's
clang/include/clang/Config/config.h)
This also adds a few files for linking to system libraries in a consistent way
if needed in llvm/utils/gn/build/libs (and moves pthread to that model).0
I'm also adding llvm/utils/gn/secondary/llvm/lib/Target/targets.gni in this
patch because $native_arch is needed for writing llvm-config.h -- the rest of
it will be used later, when the build files for llvm/lib/Target get added. That
file describes how to select which archs to build.
As a demo, also add a build file for llvm-undname and make it the default build
target (it depends on everything that can currently be built).
