eclipse.buildscript building a platform specific feature on the wrong platform

Question

I have a feature and plugin called foo, and both are win32 platform specific; however, when I call the following in my ANT script on a linux, gtk, x86 system, the feature is built, but the plugin isn't (correct).

<eclipse.buildScript elements="feature@foo" configInfo="${os},${ws},${arch}" buildDirectory="${edge.build.eclipse.loc}" baseLocation="${edge.target.eclipse.loc}" />

Is it standard that a feature should be built although it's platform specific and the build environment doesn't match?

The foo feature.xml:

<?xml version="1.0" encoding="UTF-8"?>
<feature
  id="foo"
  label="%featureName"
  version="0.0.0.200906251500"
  provider-name="%providerName"
  plugin="foo">
<install-handler/>

     version="0.0.0"/>

</feature>
