Error cross compiling device library for AArch64.

[johningve]

I believe I am facing the same issue as #11741, but for AArch64.

I am building on X86 Ubuntu 22.04, but want to target AArch64 Linux.

It looks like the sycl-compiler built without errors, but then when building the device library I get errors like:

error: unknown target triple 'unknown'

fatal error: 'cstddef' file not found

My configure command:

python buildbot/configure.py -t Release --cuda --host-target=AArch64 --cmake-gen "Unix Makefiles"

compile.txt

I have these libstdc++ packages installed:
