[Debian-med-packaging] Bug#877670: Bug#877670: Bug#877670: bcftools FTBFS on armel armhf and ppc64el

[Graham Inggs]

FWIW, I tried building htslib 1.6 and bcftools 1.6, but the issue is
still present.
I also tried building htslib 1.5 and becftools 1.5 with -fsigned-char
but that didn't help either.

Looking closer at test/test.pl, I noticed the failing test is new, so
this is not a regression.  Simply dropping the line below was enough
to get the build to succeed on armhf:
test_mpileup($opts,in=>[qw(indel-AD.1)],out=>'mpileup/indel-AD.1.out',ref=>'indel-AD.1.fa',args=>q[-a
AD]);

I'm inclined to upload with a patch skipping this still, unless there
are objections.
