If we assume 'libvirt-X.Y.Z/' (with double-digits for each version field)
as a prefix, that's upto 17 characters consumed. With a limit of 100 chars
for symlinks, we should simply make sure all our file names are 83 characters
or less
$ ./build-aux/vc-list-files | perl -e 'while (<>) { die "filename $_ too long" if length($_) > 83 }'
filename tests/cputestdata/x86-host-Haswell-noTSX+Haswell-noTSX,haswell,Haswell-noTSX-result.xml
too long at -e line 1, <> line 1280.

Daniel
