Prior to this commit, when int_vars was called for packages, it would
immediately expand the "single-dollar variables", which may be defined
in terms of variables which are not yet determined (e.g. variables
defined in package/*.mk, which are included after int_vars is called).
This is required for the next commit as after that commit, for darwin
cross-builds:
0. int_vars is defined in terms of $(1)_cc
1. $(1)_cc is defined in terms of darwin_CC
2. ... which is defined in terms of clang_resource_dir
3. ... which is defined in terms of native_cctools_clang_version
4. which is undetermined at the time when int_vars is being expanded and evaluated
After #19685 started setting LDFLAGS, the INSTALL_RPATH_USE_LINK_PATH cmake
option used in the libmultiprocess build no longer works, so it is neccessary
to set CMAKE_INSTALL_RPATH as a fallback.
It's unclear currently whether the bad interaction between
INSTALL_RPATH_USE_LINK_PATH and LDFLAGS is a bug, but the issue is reported:

Fixes#19981
By blanket passing --disable-dependency-tracking to all depends packages
we end up with some warnings like:
configure: WARNING: unrecognized options: --disable-dependency-tracking
So instead, only pass it to packages that understand it.

For normal users, --no-same-owner is default, but not so for root, where
it is assumed that root can change ownership willy-nilly. This is not
the case for privilege-limited container environments where we gaslight
the process into thinking it's root.
These add very simple sanity checks to ensure that the build/host toolchains
have not changed since the last run. If they have, all ids will change and
packages will be rebuilt.
For more complicated usage (like parsing dpkg), HOST_ID_SALT/BUILD_ID_SALT may
be used to introduce arbitrary data to the ids.
In some cases (Travis), sources and build caches may be moved around in-between
builds, and we can't necessarily trust that everything is still intact.
This introduces pre-build checks that verify against stashed checksums.
Note that this will cause all sources to be re-downloaded, since cached sources
weren't trustworthy before this.
Broken hash logic caused all depends on some platforms (osx at least) to end up
with the same build-id. Without this fix, nothing will be rebuilt when recipes
or dependencies change.
Since the last commit will force rebuilds of all depends, take the opportunity
to clean up a few other things that would trigger rebuilds as well.
- Move source stamps to the sources dir so that SOURCES_PATH is respected for
"make download".
- Only print "fetching..." when actually downloading a file.
- Avoid using non-deterministic paths for the recipe hash (patch location).
This should ensure that all builders get the same resulting build-ids.
- Use a per-package source paths. This will allow for removing old source files
in the future.
- Use a host-agnostic path for downloads which gets cleaned up properly.
Some sources are renamed after download, since the filenames don't play nice
with (for example) gitian. This fixes the rename.
Needed for OSX build as it renames a file.
