build script specific for amber ??

[Remi Forax]

Hi,
my building "farm" fails with amber [1] while it works with loom or valhalla.

The issue is that the directory used for storing the images is named
  linux-x86_64-server-release
for amber, while for the other workspaces, the directory is named
  linux-x86_64-normal-server-release

Is there a reason ?
