nanbield/x86_64: dynamic linker set to /lib64/ld-linux-x86-64.so.2

[rsflo]

Describe the bug
Executables that are cross-built using clang have the dynamic linker set to /lib64/ld-linux-x86-64.so.2 while it is actually found at /usr/lib/ld-linux-x86-64.so.2.
Build and and target are both x86_64. MACHINE is derived from poky's genericx86-64.
This is based on meta-clang commit 5170ec9 / branch nanbield (clang-17.0.4), poky tag yocto-4.3.1. meta-openembedded branch nanbield as of 19-DEC-2023.

To Reproduce
Steps to reproduce the behavior:

Build host:
$ bitbake meta-toolchain
$ "install SDK"

$ "source SDK environment file"
$ $CLANGCC -o ~/tmp/go ~/tmp/main.c
$ $READELF -p .interp ~/tmp/go
String dump of section '.interp':
[ 0] /lib64/ld-linux-x86-64.so.2

$ ls $OECORE_TARGET_SYSROOT
boot etc lib run usr var

$ ls $OECORE_TARGET_SYSROOT/lib
modules

ls $OECORE_TARGET_SYSROOT/usr/lib/ld*
[...]/usr/lib/ld-linux-x86-64.so.2

Target host:
$ /tmp/go
-bash: /tmp/go: cannot execute: required file not found

Expected behavior
Building an executable file using clang sets the dynamic linker to /usr/lib/ld-linux-x86-64.so.2

Additional context
Seems like the patches for Linux::getDynamicLinker() trip over the case the linker is neither found in /usr/lib64 nor in /lib and then defaults to /lib64/ld-linux-x86-64.so.2.
Affected patches:
0006-clang-driver-Check-sysroot-for-ldso-path.patch
0017-clang-driver-Add-dyld-prefix-when-checking-sysroot-f.patch

Previously that system was based on kirkstone and for the corresponding SDK target sysroot the linker (and a subset of shared libs) is still located in /usr and so it went fine. For nanbield all is put into /usr/lib.
(Building natively on target would probably work fine since a symlink from /usr to /usr/lib exists.)
While the latest state of master was not tried the set of relevant patches appear to be mostly identical.

There is a patch available for the mentioned ones, yet it covers x86_64 only. I'm willing to provide a complete one in case all of this makes sense :-)
