Notes for coinor-osi - reproducible builds result

Version annotated: 0.106.9-2
Identified issues:
Identifier: graphviz_nondeterministic_output
Description graphviz appears to use a non-deterministic algorithm to optimally lay out
notes optimally. This can appear in class hierarchy documentation, etc. Can
presumably affect images of all complexity but, obviously, more likely to
affect images with lots of nodes.

Identifier: records_build_flags
Description Records $CFLAGS, which vary intentionally due to the «-fdebug-prefix-map=${BUILDPATH}=.»,
«-ffile-prefix-map=${BUILDPATH}=.» or «-fmacro-prefix-map=${BUILDPATH}=.» flags.

We have a patch pending to GCC to fix this issue centrally:
.
https://gcc.gnu.org/ml/gcc-patches/2016-11/msg00182.html
.
Though the patch is currently unlikely to be merged. If/when this
is accepted, this issue should be fixed for all packages and you
should not need to fix it specifically in your package.
.
There is also a work-in-progress patch to dpkg that could address this issue:
