Notes for gcc-11 - reproducible builds result

Version annotated: 11-20201216-2
Identified issues:
Identifier: blacklisted_on_jenkins
Description Some packages have been blacklisted in our test infrastructure because
their build hangs, takes too long, spawns processes that are not killed, or
simply because they use too many resources for our current capacity. (This
is purely practical step - we would like to test these packages.)
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:
