As we've already concluded, overwriting a shared object can crash
running processes using code or data from this shared object. For
example if gdm is crashed, we may leave the system unusable :(.
Glibc tests occansionally fail due to a timeout because:
1. The hardware is slower than the developers expected.
2. Some tests use multiple or even all CPU cores internally, for e.g.
with 8 active CPU cores we may end up running 8 tests (due to -j8)
each of them uses 8 cores in the worst case, resulting a severe
congestion.
I'm almost sure nptl/tst-thread-affinity* are cases of 2.
Let's document how to rule out the timed out tests instead of making the
list of known failures longer and longer.
A Glibc update may contain locale updates, so keep
/usr/lib/locale/locale-archive synced.
Other distros are also doing this when Glibc is updated with the package
manager.
Let's change our policy to match other "rolling release" distros and
ease the procedure to fix Glibc security vulnerabilities.
Squashed the commits in xry111/update-glibc branch to keep the history
clean.

The Glibc INSTALL file says:
‘--with-headers=DIRECTORY’
Look for kernel header files in DIRECTORY, not ‘/usr/include’. ...
So --with-headers=/usr/include seems just doing nothing.
Disable building nscd in glibc.

All build times and sizes were also checked and updated as needed.
I've not bothered to write an explanation for --disable-crypt because it
will likely be the default of Glibc-2.38, then we may drop it from the
command lines.
Update the rationale for min-kernel in hostreqs. Add a note in
general.ent about the EOL of current min-kernel. Realign the
backslashes in glibc instructions.
The thread functions are in POSIX.1c, not POSIX.1b.
Both POSIX.1b and POSIX.1c are named "extensions" (plural form). And
POSIX.1b is titled "Real-time" instead of "Realtime".
Please try not to use the "replace" feature of the text editor blindly.
Appendix C of the GNU C Library Reference Manual clearly says:
'--disable-werror'
By default, the GNU C Library is built with '-Werror'. If you wish
to build without this option (for example, if building with a newer
version of GCC than this version of the GNU C Library was tested
with, so new warnings cause the build with '-Werror' to fail), you
can configure with '--disable-werror'.
