Andrei Gherzan ec6f9694ea qemu: Backport patch to avoid assertion fails on icache line size
Due to a bug in glibc 2.33, the value of the icache line size is now
reported as unsupported option. This breaks qemu at runtime with:

cacheinfo.c:182: init_cache_info: Assertion `(isize & (isize - 1)) == 0'
failed.
Aborted (core dumped)

We haven't caught this one yet because we were already on qemu 5.2.0
when we started to play with glibc 2.33 so it was only reproducible on
dunfell.

QEMU Emulation Targets
======================

To simplify development, the build system supports building images to
work with the QEMU emulator in system emulation mode. Several architectures
are currently supported in 32 and 64 bit variants:

  * ARM (qemuarm + qemuarm64)
  * x86 (qemux86 + qemux86-64)
  * PowerPC (qemuppc only)
  * MIPS (qemumips + qemumips64)

Use of the QEMU images is covered in the Yocto Project Reference Manual.
The appropriate MACHINE variable value corresponding to the target is given
in brackets.
