for a build configured with...

./configure --prefix=/sw --program-transform-name=s/tar/gtar/ 
--infodir=/sw/share/info --libexecdir=/sw/lib --disable-dependency-tracking 
FORCE_UNSAFE_CONFIGURE=1

The regression occurs with and without coreutils installed. I have also 
attached the complete testsuite.log
bzip2 compressed.
