clang-21 decides to emit wcslen call on arm architecture
klibc does not provide widechar support so it should not
be used.

for what changes are needed, and sed commands that can be used to make them en masse.
I've verified that bitbake -c patch world works with these, but did not run a world
build; the majority of recipes shouldn't need further fixups, but if there are
some that still fall out, they can be fixed in followups.

Following reproducible-builds.org recommendations, using compiler flags
like -ffile-prefix-map or -fdebug-prefix-map allows replace build-time
paths by install-time ones in the debugging sections of binaries.
Variable DEBUG_PREFIX_MAP set these flags correctly in yocto build
context to guarantee reproducible builds.

There is new patch-status QA check in oe-core:
https://git.openembedded.org/openembedded-core/commit/?id=76a685bfcf927593eac67157762a53259089ea8a
This is temporary work around just to hide _many_ warnings from
optional patch-status (if you add it to WARN_QA).
This just added
Upstream-Status: Pending
everywhere without actually investigating what's the proper status.
This is just to hide current QA warnings and to catch new .patch files being
added without Upstream-Status, but the number of Pending patches is now terrible:
