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

https://git.yoctoproject.org/poky/commit/?id=4dd321f8b83afecd962393101b2a6861275b5265
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.
