The generated-sources.tar.gz artifact on android-armv7 builds includes this entry:
Which means that
tar returns an error code after untarring it:
tar: Removing leading `../' from member names
tar: ../android-ndk/sources/android/cpufeatures/cpu-features.c: Member name contains '..'
tar: Exiting with failure status due to previous errors
It seems like this bogus entry should either be stripped from the tarball, or it should be relocated to a better location. The stripping could happen in package_generated_sources.py pretty easily.
This bad entry and failure to untar the file causes a searchfox run failure when I try to include android stuff.
