Bug#872464: zimlib: FTBFS all over the place due to symbols diff

[James Clarke]

Source: zimlib
Version: 2.0.0-1
Severity: serious

Hi,
Once again zimlib FTBFS due to symbols file diffs. Please at least *try*
to get a working symbols file; you can at least build amd64 locally, and
we have porterboxen for a reason...
