I've added info about how to get access to test environments here:
  
https://git.savannah.gnu.org/gitweb/?p=gnulib/maint-tools.git;a=blob;f=platforms/test-environments.txt
  
https://git.savannah.gnu.org/gitweb/?p=gnulib/maint-tools.git;a=tree;f=platforms/environments

In particular, the compile farm has 4 machines with aarch64 CPU.
Maybe you also have an Android phone with aarch64 CPU on it (and
can install Termux in 64-bit mode on it)?

It is correct that emulators sometimes don't implement the need for
cache invalidation correctly; I observed this for mips too. But QEMU
is quite good nowadays; it's better than nothing.
