Merge #18004: build: don't embed a build-id when building libdmg-hfsplus 
cb9e88e73a build: don't embed a build-id when building libdmg-hfsplus (fanquake)

Pull request description:

  There was a [reproducibility issue (IRC logs)](http://www.erisian.com.au/bitcoin-core-dev/log-2020-01-25.html) with the osx `0.19.1rc1` gitian builds. The `build-id` embedded into the `dmg` tool was mismatching. It's possible that differing versions of binutils/ld were the cause.

  While it was resolved after rebuilding the base gitian image, whether an upstream package issue or fluke, we can remove the possibility of it happening in future by just not embedding a build-id into the `dmg` tool at all. Can close if it's not deemed worth it.

  You can test this change using the following:

  ```bash
  # build libdmg
  make native_libdmg-hfsplus_built -C depends/ HOST=x86_64-apple-darwin16 -j6 V=1

  # master
  readelf --string-dump .note.gnu.build-id /bitcoin/depends/work/build/x86_64-apple-darwin16/native_libdmg-hfsplus/7ac55ec64c96f7800d9818ce64c79670e7f02b67-3830944ef98/build/dmg/dmg

  String dump of section '.note.gnu.build-id':

Bitcoin Core integration/staging tree

https://bitcoincore.org

What is Bitcoin?

Bitcoin is an experimental digital currency that enables instant payments to anyone, anywhere in the world. Bitcoin uses peer-to-peer technology to operate with no central authority: managing transactions and issuing money are carried out collectively by the network. Bitcoin Core is the name of open source software which enables the use of this currency.

For more information, as well as an immediately usable, binary version of the Bitcoin Core software, see https://bitcoincore.org/en/download/, or read the original whitepaper.

License

Bitcoin Core is released under the terms of the MIT license. See COPYING for more information or see https://opensource.org/licenses/MIT.

Development Process

The master branch is regularly built and tested, but is not guaranteed to be completely stable. Tags are created regularly to indicate new official, stable release versions of Bitcoin Core.

The contribution workflow is described in CONTRIBUTING.md and useful hints for developers can be found in doc/developer-notes.md.

Testing

Testing and code review is the bottleneck for development; we get more pull requests than we can review and test on short notice. Please be patient and help out by testing other people's pull requests, and remember this is a security-critical project where any mistake might cost people lots of money.

Automated Testing

Developers are strongly encouraged to write unit tests for new code, and to submit new unit tests for old code. Unit tests can be compiled and run (assuming they weren't disabled in configure) with: make check. Further details on running and extending unit tests can be found in /src/test/README.md.

There are also regression and integration tests, written in Python, that are run automatically on the build server. These tests can be run (if the test dependencies are installed) with: test/functional/test_runner.py

The Travis CI system makes sure that every pull request is built for Windows, Linux, and macOS, and that unit/sanity tests are run automatically.

Manual Quality Assurance (QA) Testing

Changes should be tested by somebody other than the developer who wrote the code. This is especially important for large or high-risk changes. It is useful to add a test plan to the pull request description if testing the changes is not straightforward.

Translations

Changes to translations as well as new translations can be submitted to Bitcoin Core's Transifex page.

Translations are periodically pulled from Transifex and merged into the git repository. See the translation process for details on how this works.

Important: We do not accept translation changes as GitHub pull requests because the next pull from Transifex would automatically overwrite them again.

Translators should also subscribe to the mailing list.
