FWIW, I just ran a build on x86_64 for aarch64 with poky, meta-oe and
meta-qt5 in their 'rocky' branches, and it worked just fine.

On my machine:

  build/src/3rdparty/chromium/tools/gn/out/Release/gn: ELF 64-bit LSB
executable, x86-64, version 1 (GNU/Linux), dynamically linked,
interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.6.32,
BuildID[sha1]=aae0a9a51c01e07511994ab36a0a6d4d2a645364, stripped

I can't tell you what's wrong on your end, but at least it doesn't seem
to be a general problem.
