Release 1.21.21

This reverts commit f9187c8b.

This reintroduces the loong64 CPU support that got reverted. The GNU
triplet and the multiarch tuples have gone back upstream to the previous
agreed names.

This caused the author checks to fail, and consequently the CI pipelines
too. Unfortunately the release script did not catch this, probably due
to not properly installing the build dependencies.

This kind of file includes translated entries, which causes spelling
check false positives, and makes the author tests and CI systems
checking those fail.

The non-breaking space before the colon seems to be confusing po4a which
ends up using it for all subsequent spaces within the I<> markup. Move
the non-breaking space outside the I<> markup to avoid the issue.

There was a missing 1 in the version.

Some of these are valid, but we'll fix them in the soon to open 1.22.x
series. This should make the CI systems based on Debian unstable
checking author mode, get back to normal.

This reverts commit 321e479b.

This arch which was supposedly already defined, with an agreed ABI,
GNU triplet and dpkg multiarch paths, seems to want to redefine all
these. There is no clear rationale for why this is happening at this
point in time, while patches for at least gcc have been submitted
with no coordination (which ended up being applied).

The handling of this is less than ideal. Until the whole situation
gets clarified, the safest way is to revert the support. It can be
reintroduced once things clear out.

The recently added lto handling for Ubuntu, did not take into account
that the DEB_BUILD_OPTIONS and DEB_BUILD_MAINT_OPTIONS environment
variables are parsed and their options applied just after setting the
defaults, and before applying any arch-specific mask.

We add a new init_build_features() internal method, which sits between
these two actions, so that the Ubuntu vendor module can modify the
defaults before any user or maintainer override are applied.

The source ChangeLog.old file might have different permissions depending
on the umask during the source package unpack. Copy the file without
any flags, and then explicitly set known permissions on the result file.

This should fix the build on reproducible variants.
