6b5506a286 Fix Qt's rcc determinism for depends/gitian (Fuzzbawls)
Pull request description:
With the update to Qt 5.9 having been merged, Qt's `rcc` tool now embeds a file's last modified time in it's output. Since the build system generates temporary files for all locale translations (`*.qm` files) at build time, the resulting `qrc_bitcoin_locale.cpp` file was always being generated in a non-deterministic way.
This is a backport of https://bugreports.qt.io/browse/QTBUG-62511, which is included in Qt versions 5.11+, that allows for an environment variable (`QT_RCC_SOURCE_DATE_OVERRIDE`) to override the behavior described above. This environment variable is in turn set in the gitian descriptors, as that is where determinism is vital for release purposes.
Prior to this, the `qt_libbitcoinqt_a-qrc_bitcoin_locale.o` object file (included into `libbitcoinqt.a`) was returning a different `sha256sum` for each and every build, regardless of file contents change, thus breaking determinism in the resulting binaries.
This should fix#13731

359e2e3525 depends: Add RISC-V support (Wladimir J. van der Laan)
Pull request description:
This adds support for riscv32 and riscv64 builds to the depends system.
The change consists of documentation and build system changes. The most significant change is an update of `config.sub` and `config.guess` inside zeromq patch, as the current version does not recognize the `riscv*` host tuples (there's no new version of ZeroMQ yet with newer ones).
Good thing: RISC-V 64-bit toolchain packages can be installed out of the box on Ubuntu 18.04+.
I would also like to add RISC-V 64-bit executables to gitian, but this will not be possible until #12511 .

The patch Bitcoin Core has been maintaining for mac_alias was pulled by the mac_alias maintainer in commit 4f31cb084c1c6a8626128b0b00842020b6db9037. Delete the patch and remove the patch from the depends system.
Note that this PR won't be complete until a new version of mac_alias containing the path has been released, and the depends system is updated to reflect the new version.
This is broken for a number of reasons, including:
- g++ understands "-static-libstdc++ -lstdc++" to mean "link against whatever
libstdc++ exists, probably shared", which in itself is buggy.
- another stdlib (libc++ for example) may be in use
ld64 is threaded, and uses a worker for each CPU to parse input files. But
there's a bug in the parser causing dependencies to be calculated differently
based on which files have already been parsed.
As a result, builders with more CPUs are more likely to see non-determinism.
This looks to have been fixed in a newer version of ld64, so just disable
threading for now. There's no noticible slowdown.
This contains a few hacks very specific to Qt's buildsystem. These can be
reverted once we split the build between native and target builds.
Qt's build contains a circular dependency when not using a system zlib.
By far the easiest fix is to switch to a system zlib, rather than Qt's own.
However, that confuses Qt's cross build which assumes that when using a system
zlib, it should also find a system (native) zlib for native tools. The build
breaks if that zlib is not present.
To solve this:
1. Always use a system zlib rather than the one provided by qt
2. Set force_bootstrap, which instructs the build tools to be built as though
we're cross-compiling (build != target)
3. For build tools, use qt's internal zlib so that a native zlib is not
required.
Step 3 means that if any zlib headers are found by the native build, it will
confuse Qt's internal zlib build. So we also need to make sure that the target
headers/libs aren't found. To do so, specify that our
cflags/cxxflags/cppflags/ldflags only apply for non-host builds.
