check-artifact.sh was broken by the update to Gradle 2.10. We think the
update to Gradle 2.8 caused the POM to start being generated, but this
now fixes it to have the correct contents.
Using addFilter _disables_ the normal POM, so we use setFilter instead.
Fixes#1360
- Stop defining custom architectures because VisualCpp toolchain doesn't
allow it. Reference to built-in architectures 'x86' and 'x86_64' since
they are supported by all toolchains.
- Remove 'local_arch' from platforms. For unsupported platform, we just
do not specify the target.
- Target no more than one platform at a time. This simplifies the build
script a lot.
- Remove the TARGET_ARCHS environment variable. Add system property
``arch`` to override ``osdetector.arch``.
- Add ``vc.disable`` to override the default choice of VisualCpp on
Windows.
- Add ``vc.`` prefix to the properties that are only used with VC++
