alpine docker configuration fails rust tests

[Richard Henderson]

Hiya,

Our Alpine docker image isn't quite right, and fails testing for rust:

But what's even more annoying is that --disable-rust doesn't suppress this check.

Thanks in advance,

Bah.  I was too quick to point the finger.
It's a different part of the tooling that's in error:

$ make J=8 V=1 docker-test-full@alpine EXTRA_CONFIGURE_OPTS=--disable-rust
...
podman run --rm   --userns keep-id   --security-opt seccomp=unconfined  --net=none -e 
TARGET_LIST= -e EXTRA_CONFIGURE_OPTS="--disable-rust" -e TEST_COMMAND="" -e V=1 -e J=8 -e 
DEBUG= -e SHOW_ENV=  -v $HOME/.cache/qemu:$HOME/.cache/qemu -e

qemu/alpine /var/tmp/qemu/run test-full
...
Configure options:
--enable-werror --prefix=/tmp/qemu-test/install --disable-rust --enable-rust

Clearly EXTRA_CONFIGURE_OPTS should be added at the end.
