Any file:// file in an SRC_URI can become machine specific if placed in a machine subdir in the search path. That said, I don't know why the automatic behavior of setting package_arch in that case is something that needs to be disabled for tslib. I'd suggest using git-blame to examine the commits which added this variable. -- Christopher Larson clarson at kergoth dot com Founder - BitBake, OpenEmbedded, OpenZaurus Maintainer - Tslib Senior Software Engineer, Mentor Graphics
