- bump rest of the workflows (windows, macos, distrocheck).
- non-native virtualized envs have 2 CPUs, bump down accordingly.
(for `vmactions/omnios-vm` it's just a guess.)
- bump all to nproc + 1.

For better build performance. Dependency tracking causes a build
overhead while compiling to help a subsequent build, but in CI there is
never one and the extra work is discarded.
Closes#13794
PowerShell works (after a steep development curve), but one property of
it stuck and kept causing unresolvable usability issues: With
`$ErrorActionPreference=Stop`, it does abort on failures, but shows only
the first line of the error message. In `Continue` mode, it shows the
full error message, but doesn't stop on all errors. Another issue is
PowerShell considering any stderr output as if the command failed (this
has been improved in 7.2 (2021-Nov), but fixed versions aren't running
in CI and will not be for a long time in all test images.)
Thus, we're going with bash.
Also:
- use `-j2` with autotools tests, making them finish 5-15 minutes per
job faster.
- omit `POSIX_PATH_PREFIX`.
- use `WINDIR`.
- prefer forward slashes.

Ref: #12444Fixes#12560Closes#12572
This is done by cross-compiling under regular x86_64 Linux. Since the
kernel offers backwards compatibility, the binaries can be tested as
normal.
