Splitting llvm, tblgen into their own recipes means we
have to ensure nativesdk clang build can find these tools
in native sysroot, which is would previously build and use
on its own.

I spotted this error in the autobuilder:
https://autobuilder.yoctoproject.org/valkyrie/#/builders/61/builds/2266/steps/12/logs/stdio
Could you please take a look?
Thanks!

Logs are showing clang-native failure while the change in this patch is
limited to nativesdk clang. So it is unrelated to this patch
However change seems to be related to llvm recipe separation series since
clang is building this tool during its build and trying to use it from its
build area but it’s perhaps not finding libllvm from native sysroot

I poked at the worker on AB where it is failing, I think there is a
cmake patch which is problematic.
https://patchwork.yoctoproject.org/project/oe-core/patch/20250915145134.192581-1-ross.burton@arm.com/
clang builds some tools during build and links them to in-tree libLLVM
if it is built in monolithic builds ( which we do ) and this option
omits build time rpaths which causes this problem.
