e9189a750b237eba1befc6b16c12c2cee3e0176c build: more robustly check for fcf-protection support (fanquake) Pull request description: When using Clang 7, we may end up trying to use the flag when it won't work properly, which can lead to confusing errors. i.e: ```bash /usr/bin/ld: error: ... <corrupt x86 feature size: 0x8> ``` Use `AX_CHECK_LINK_FLAG` & `--fatal-warnings` to ensure we wont use the flag in this case. We do this as even when the error is emitted, compilation succeeds, and the binaries produced will run. This means we can't just check if the compiler accepts the flag, or if compilation succeeds (without or without `-Werror`, and/or passing `-Wl,--fatal-warnings`, which may not be passed through to the linker). This was reported by someone configuring for fuzzing, on Debian 10, where Clang 7 is the default. See here for a minimal example of the problematic behaviour: https://gist.github.com/fanquake/9b33555fcfebef8eb8c0795a71732bc6 ACKs for top commit: pstratem: tested ACK e9189a750b237eba1befc6b16c12c2cee3e0176c MarcoFalke: not an ACK e9189a750b237eba1befc6b16c12c2cee3e0176c , I only tested configure on my system (gcc-10, clang-11): hebasto: ACK e9189a750b237eba1befc6b16c12c2cee3e0176c, tested with clang-7, clang-10 and gcc: the `-fcf-protection=full` is not applied for clang-7, but applied for others compilers.

What is Dash?
Dash is an experimental digital currency that enables instant, private payments to anyone, anywhere in the world. Dash uses peer-to-peer technology to operate with no central authority: managing transactions and issuing money are carried out collectively by the network. Dash Core is the name of the open source software which enables the use of this currency.
Pre-Built Binary
For more information, as well as an immediately usable, binary version of the Dash Core software, see https://www.dash.org/downloads/.
License
Dash 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 meant to be stable. Development is normally done in separate branches.
Tags are created to indicate new official,
stable release versions of Dash 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 Dash 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 follow the forum.
