Hi Guix,

the first patch replaces a Makefile-patching build phase with
make-flags.  The second patch makes samtools install its libbam
library.

The third patch adds the most recent version of the 0.1 line of
samtools.  The input and output formats differ greatly from that used
and produced by samtools 1.x (which has already been packaged as
"samtools") and is still used in many bioinformatics pipelines.
