[Android-tools-devel] Bug#976891: Bug#976891: fastboot exits with "fake placeholder until fastboot builds" message

[Hans-Christoph Steiner]

As far as I know, the blocker for fastbook is android-platform-art.  It 
has a crazy upstream build system.  Right now, it almost building, but 
the build is currently dying on this error:
