Directory size is an install-time filesystem specific implementation
detail, build-time just doesn't have a clue. If we want to try taking
directory sizes into account, this needs to happen in the disk space
checking at install time.
It also helps making builds a bit more reproducable (PR #229)
(cherry picked from commit 2cf7096ba534b065feb038306c792784458ac9c7)
This macro offers %{_smp_mflags}, but without the -j prefix, to signify
the configured number of processor cores to use.
We can use this to pass that number to utilities that do not understand
the -j number syntax, for example:
`cmake --build %_cmake__builddir --verbose --parallel %_smp_build_ncpus'

We preserve ALT semantics though.
This is required to guarantee that no python3 req/prov are accidentally
lost because python3.{req,prov} are not installed.
Unlike rpm-build-python3, rpm-macros-python3 can be installed without
python3, so no extra dependencies are pulled in.
If rpm-build-python3 is not installed but python3.{req,prov}.files
decide that python3.{req,prov} have to be invoked, the latter will issue
an error.
The idea is that rpm-macros-python could be installed without python2,
consequently, python2 will no longer be installed by default, but no
python2 req/prov would be lost because of that change because,
if a python2 module package or a package containing a python2 script
would miss to pull in python2, it would fail to build.
When there is number after "T" (suggested number of threads or "0" for
getncpus), lzopen_internal() mode parser would skip one byte, and when
it's at the end of the string it would then parse undesired garbage from
the memory, making intermittent compression failures.

Mode flags could change from what is specified in defines and errors
could happen before any other descriptive messages would appear, but
it's useful to know some additional info about xz compression to debug
multi-threading memory failures.

Liblzma is non-robust on memory allocation problems - while it works
well on 64-bit architectures with plenty of RAM, it's problematic on
32-bit architectures when multi-threading is used.
Try another workaround: instead of just guessing the best delta, move
half of the current (512MiB) delta into 'guard malloc' allocation test
of what LZMA encoder memusage would return.
This is definitely hackish (and vulnerable to toctou), but it's that
much we could do without significantly reworking stream_encoder_mt.

Recent changes left downgradeLzmaLevel dysfunctional (because it does
not recognize 'T'). In my view, the only advantage of XZ over LZMA is
that XZ can can split input into blocks and compress them in parallel
(resulting in a speed-up). Other advantages, such as a checksum, are
immaterial for our purpose (because the package manager must verify the
integrity of a package beforehand). Therefore, downgradeLzmaLevel will
also downgrade XZ->LZMA automatically, for payloads smaller than
5*dictSize (the default blockSize being 3*dictSize, so that there are
at least two blocks, the second block not too small).

`strip' is called by `install -s` that could occur in unpatched
Makefiles, breaking debuginfo generation.
Try to catch `install` invocations via:
- %__install macro used in `make INSTALL=`.
- Prefix PATH with `/usr/libexec/rpm-build` with install and strip
wrappers.

For some systems 128 MiB delta is not enough for `w7T.xzdio`. Found by
experiment that 256 MiB is enough.

Based on commit a60f36a55 by Per Øyvind Karlsen. Original commit message:
As 32 bit build suffers under the limitation of 32 bit address space,
regardless of it's environment would be ie. 64 bit and not have this
constration, rpm must make sure not to exceed this memory limitation.
When using multithreaded xz compression, the number of threads used will
increase the memory usage, making it necessary to check the memory
required with the number of threads to be used.
Number of compression threads will therefore be kept reduced untill
amount of memory required won't exceed this limitation.
For 32 bit binaries running under 64 bit host environment, where less
available memory will be reserved for kernel, easing memory constraints,
determination of this will be done by a combination of checking host
arch as well as whether 32 bit personality flag is set, thereby still
allow a sligthly greater memory usage for such cases to avoid
imposing unnecessatry limitations under such environments.
Changes from the original commit:
- Do not call uname(2).
- Limits are increased.
- Do not call lzma_memlimit_set().
- No message about thread limitation.
