Bug#948518: RM: grabix [s390x] -- ROM; upstream htslib broke s390x and is holding up several transitions

[Michael R. Crusoe]

Package: ftp.debian.org
Severity: important

A follow on to https://bugs.debian.org/948092 as I forgot to include
grabix in the list; this appears to be holding up the transition to
testing if I'm reading https://release.debian.org/britney/update_output.txt 
correctly.

Thanks!
