all the basic command like chgrp/chmod/chown/mkdir/touch
will first search /use/lib/locale/locale-archive. if failed,
then search the exact locale like /usr/lib/locale/zh_CN.
right now we don't have locale-archive and this will cause the
basic command's performance regression, so add it.
here the details:
libio: Ensure output buffer for wchars bug 28828
libio: libio Flush onlu _IO_str_overflow must not return EOF bug 28949
linux: Fix _closefrom_fallback iterates until max int bug 28993
backport the following seven patches
malloc: Add madvise support for Transparent Huge Pages

Linux 5.13 adds a PTRACE_GET_RSEQ_CONFIGURATION constant, with an
associated ptrace_rseq_configuration structure.
Add this constant to the various sys/ptrace.h headers in glibc, with
the structure in bits/ptrace-shared.h (named struct
__ptrace_rseq_configuration in glibc, as with other such structures).
In Kunpeng-920, the performance of strcmp deteriorates only
when the 16 to 23 characters are different.Or the string is
only 16-23 characters.That shows 2 misses per iteration which
means this is a branch predictor issue indeed.
In the preceding scenario, strcmp performance is 300% worse than expected.
Fortunately, this problem can be solved by modifying the alignment of the functions.

The default debuginfo management mechanism is not deleted.
Instead, Use the default macro of RPM.
/usr/lib/rpm/openEuler/macros defines:
"""
%install% {?_Enable Debug Package:% {?Build subdirectory:% {debug package}\
%%Install\
%{nil}
"""
There are two changes:
1. The source files in /usr/src are
correctly packed into the debugging source.
2. The debugging file contains the glibc version number.
The CI detects the file change. However, I think this is caused by the CI.
