The Yocto Project builds and uses gcc cross compilers and we believe
our builds to be reproducible when configured to be.

We do use SOURCE_DATE_EPOCH and -ffile-prefix-map=.

We're in the final stages of putting together tests which actually test
and prove that in our CI setup, I'm looking forward to being able to
announce those here soon.
