Problem description & steps to reproduce

While working on reproducible builds for openSUSE I found that
with #11315 added, there was only one reproducibility-issue left and I found that this goes away with the -DGGML_NATIVE=OFF cmake option.

I wonder if we could have cmake notice the $SOURCE_DATE_EPOCH environment variable to indicate that a reproducible build is wanted and change the default to OFF, similar to when cross-compilation is detected.
