Merge tag 'xry111/update-20231113' into trunk

There are some suspicious "nptl/tst-robust" test failures in Glibc, but
all other test results are clean.  To be diagnosed...

And note that jhalfs needs an update to work with the merged parallelism
changes.

+    For many modern systems with multiple processors (or cores) the
+    compilation time for a package can be reduced by performing a "parallel
+    make" by telling the make program how many processors are available via
+    a command line option or an environment variable.  For instance, an Intel
+    Core i9-13900K processor has 8 P (performance) cores and
+    16 E (efficiency) cores, and a P core can simultaneously run two threads
+    so each P core are modeled as two logical cores by the Linux kernel.
+    As the result there are 32 logical cores in total.  One obvious way to
+    use all these logical cores is allowing <command>make</command> to spawn
+    up to 32 build jobs.  This can be done by passing the
+    <parameter>-j32</parameter> option to <command>make</command>:
