Notes for kookbook - reproducible builds result

Version annotated: 0.1.0-2
Identified issues:
Identifier: ftbfs_due_to_f-file-prefix-map
Description An example of failure related to this are programs that expect
__FILE__ to expand to some absolute path, but instead finding themselves
a relative one.
.
In our unstable and experimental build systems we export
DEB_BUILD_OPTIONS=reproducible=+all
that makes dpkg-buildflags enable the reproducible/fixfilepath feature, adding
-ffile-prefix-map=BUILDPATH=.
to CFLAGS, CXXFLAGS, OBJCFLAGS, OBJCXXFLAGS, GCJFLAGS, FFLAGS and FCFLAGS.
 

Our notes about issues affecting packages are stored in notes.git and are targeted at packages in Debian in 'unstable/amd64' (unless they say otherwise).
