Comment 12 for bug 1701798

> You can probably also work around this by creating an empty ld.so.cache in the QEMU_LD_PREFIX directory, though it's awkward if you wanted that to be the /usr/whatever directory.

Indeed, qemu already analyzes the QEMU_LD_PREFIX, stores a cache of its contents in the static variable 'base', and uses it in the do_openat() function.

The following provides a workaround for me that does not require any change to qemu:

sudo mkdir -p $QEMU_LD_PREFIX/etc
sudo ln -s /nonexistent $QEMU_LD_PREFIX/etc/ld.so.cache
