Jun Wu 41ccbe9f8d hg.rust: add BuildInfo symbols 
Summary:
BuildInfo symbols are generated for fbcode binaries, and scanned by the
internal procprint tool. The procprint tool also scans hg binaries, but cannot
extract any build information.

The procprint data is used by Push4Push to find out job owners running ancient
software.

This diff inserts BuildInfo symbols so Push4Push (and we) can use them to
figure out people running old versions of hg and send tasks to them.

Note rpmbuild strips symbols by default and is hard to customize. For now, I
just disable the debuginfo packages to preserve the symbols. If space usage or
runtime performance becomes an issue, we can try other workarounds (ex. provide
a shim of `%_find_debuginfo_dwz_opts` that skips `hg.rust`, or provide a shim
of `%__strip`, etc).

By default, the symbols only get added when `setup.py` is run by `rpmbuild`.
So `make local` won't rebuild `hg.rust` every time.

Mercurial
=========

Mercurial is a fast, easy to use, distributed revision control tool
for software developers.

Basic install::

 $ make            # see install targets
 $ make install    # do a system-wide install
 $ hg debuginstall # sanity-check setup
 $ hg              # see help

Running without installing::

 $ make local      # build for inplace usage
 $ ./hg --version  # should show the latest version

See https://mercurial-scm.org/ for detailed installation
instructions, platform-specific notes, and Mercurial user information.
