Notes for biboumi - reproducible builds result

Version annotated: 4.0-1
Identified issues:
Identifier: captures_kernel_version_via_CMAKE_SYSTEM
Description Uses CMAKE_SYSTEM, which embeds `uname -sr` output; the -r (version) varies.
.
Instead, use CMAKE_SYSTEM_NAME (`uname -s`), which shouldn't vary.
.
Parent issue: captures_kernel_version
Identifier: captures_build_path_via_assert
Description Absolute paths to source file names are embedded through assert(), which
embeds the value of the __FILE__ macro in the .data section, or via
filenames in debug symbols, which shows in the .text and .debug_str sections.
.
We have a pending patch to GCC to fix this in one central place.
.
https://gcc.gnu.org/ml/gcc-patches/2016-11/msg00182.html
.
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.
