Notes for atf - reproducible builds result

Version annotated: 0.21-1
Identified issues:
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:

Identifier: paths_vary_due_to_usrmerge
Description eg. /bin/ vs /usr/bin/ or /lib vs. /usr/lib
Bugs noted: 1039808+: "atf: reproducible-builds: Embedded path to bash in various binaries"
Comments: Embeds CFLAGS and CXXFLAGS via ATF_BUILD_CFLAGS and ATF_BUILD_CXXFLAGS - see m4/runtime-tool.m4 etc.
.
Passing ATF_SHELL=/bin/bash to dh_auto_build works around usrmerge issues.
