Notes for epm - reproducible builds result

Version annotated: 4.2-12
Identified issues:
Identifier: captures_kernel_variant
Description Similar to captures_kernel_version, but specifically refers to capturing
x86_64 vs i686. This can (currently) happen when testing the i386
architecture as we use a 64-bit kernel with a 32-bit Debian userland.
.
Notably, we do not use `linux32` to emulate the 32 bit personality when
running those builds, as normally this hides packages that are making use of
`uname` to detect the host architecture when they really should not.
 

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).
