e8cd3700ee devtools: Integrate ARCH_MIN_GLIBC_VER table into MAX_VERSIONS in symbol-check.py (W. J. van der Laan)
a33381acf5 devtools: Add xkb version to symbol-check (W. J. van der Laan)
19e598bab0 devtools: Fix verneed section parsing in pixie (W. J. van der Laan)
Pull request description:
I misunderstood the ELF specification for version symbols (verneed): The `vn_aux` pointer is relative to the main verneed record, not the start of the section.
This caused many symbols to not be versioned properly in the return value of `elf.dyn_symbols`. This was discovered in #21454.
Fix it by correcting the offset computation.
- xkb versions symbols (using the prefix `V`), as this library is used by bitcoin-qt, add it to the valid versions in `symbol-check.py`
This unfortunately brings to light some symbols that have been introduced since and weren't caught (from a gitian compile of master):
```

The (ancient) versions specified here were deceptive. Entries older than
MAX_VERSIONS['GLIBC'], which is 2.17, are ignored here. So reorganize
the code to avoid confusion for other people reading this code.

Clangs Darwin driver should infer the SDK version used during compilation, and
forward that through to the linker. Add a check that this has been done, and the
expected SDK version is set.
Should help prevent issues like #21771 in future.
We use linker flags (-Wl,--major/minor-subsystem-version) to set the
minimum required version of Windows needed to run our binaries. This
adds a sanity check that the version is being set as expected.
We use a compile flag (-mmacosx-version-min) to set the minimum required
version of macOS needed to run our binaries. This adds a sanity check
that the version is being set as expected.
Because only macOS wasy mentioned, I was unsure if this would be a macOS specific tool. I guess Linux is more used than Mac, so Linux guide should be there, too.
remove fix_configure_mac.patch
Fixed upstream: https://bugreports.qt.io/browse/QTBUG-67286
remove fix_riscv64_arch.patch
Was fixed upstream in 6a39e49a6cdeb28a04a3657bb6a22f848d5dfa9d

Fixed upstream in https://bugreports.qt.io/browse/QTBUG-62511
remove freetype_back_compat.patch
By the time we ship a release with Qt 5.12, we'll certainly no-longer be
supporting Ubuntu 14.04 and Ubuntu 16.04 ships with FreeType 2.6.1,
which is new enough that using the symbol is no-longer an issue.
The renaming of FT_Get_X11_Font_Format() happened in FreeType 2.6

a0a771843f contrib: Changes to checks for PowerPC64 (Luke Dashjr)
634f6ec4eb contrib: Parse ELF directly for symbol and security checks (Wladimir J. van der Laan)
Pull request description:
Instead of the ever-messier text parsing of the output of the readelf tool (which is clearly meant for human consumption not to be machine parseable), parse the ELF binaries directly.
Add a small dependency-less ELF parser specific to the checks.
This is slightly more secure, too, because it removes potential ambiguity due to misparsing and changes in the output format of `elfread`. It also allows for stricter and more specific ELF format checks in the future.
This removes the build-time dependency for `readelf`.
It passes the test-security-check for me locally, ~~though I haven't checked on all platforms~~. I've checked that this works on the cross-compile output for all ELF platforms supported by Bitcoin Core at the moment, as well as PPC64 LE and BE.

6690adba08 Warn when binaries are built from a dirty branch. (Tyler Chambers)
Pull request description:
- Adjusted `--version` flag behavior in bitcoind and bitcoin-wallet to have the same behavior.
- Added `--version` flag to bitcoin-tx to match.
- Added functionality in gen-manpages.sh to error when attempting to generate man pages for binaries built from a dirty branch.

Check both failure cases:
- Use a glibc symbol from a version that is too new
- Use a symbol from a library that is not in the allowlist
And also check a conforming binary.
Adding a similar check for Windows PE can be done in a separate PR.
