[Debian-med-packaging] Bug#880236: python-biopython: FTBFS: Test failures

[Peter Cock]

The key part of the log
http://aws-logs.debian.net/2017/10/30/python-biopython_1.70+dfsg-2_unstable.log
is this bit:

======================================================================
FAIL: test_index (test_BWA_tool.BwaTestCase)
Test for creating index files for the reference genome fasta file
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/<<BUILDDIR>>/python-biopython-1.70+dfsg/.pybuild/pythonX.Y_2.7/build/Tests/test_BWA_tool.py",
line 102, in test_index
    % (cmdline, stdout))
AssertionError: FASTA indexing failed:
bwa index -a bwtsw BWA/human_g1k_v37_truncated.fasta
Stdout:

----------------------------------------------------------------------

This has been reported upstream, and we suspect it is due to a change
in the command line tool bwa:
