* with read-only PREMIRROR (e.g. mounted over NFS or CIFS
and referenced as file:///mnt/premirror) we cannot use
BB_GENERATE_MIRROR_TARBALLS because all git2_abc.git.tar.gz
files later became just symlinks to read-only location in PREMIRROR
(it works fine on first build and for new components, because
at that time there isn't tarball on PREMIRROR yet).
ERROR: Fetcher failure: Fetch command failed with exit code 141, output:
tar (child): /build/downloads/git2_abc.git.tar.gz: Cannot open: Read-only file system
tar (child): Error is not recoverable: exiting now
