With the huge number of QEMU targets, a default configuration will take
a very long time to rebuild. When developing most code changes, it is
sufficient to test compilation with a single target - rebuilding all
targets just extends compile times while not detecting any new problems.
Developers will often thus specify a single target for configure,
commonly matching the host architecture. eg
./configure --target-list=x86_64-softmmu
This works fine, but is a bit of a verbose thing to type out everytime
configure is invoked. There are already short-hand args to disable all
user targets, all softmmu targets, or all tcg targets. This adds one
further shorthand to disable all non-native architecture targets.
./configure --native

Suggestions welcomed for better names than --native, but bear in mind
the goal is to minimise amount of typing so nothing too verbose, hence
why I didn't do something like --disable-non-native ...
