Hi,
Whilst working on the Reproducible Builds effort [0], we noticed that
pan could not be built reproducibly.
This is because the /usr/bin/pan binary embedded the kernel version
name and version number:
│ │ │ ├── ./usr/bin/pan
[…]
│ │ │ │ ├── strings --all --bytes=8 {}

A patch is attached that has the effect that, if SOURCE_DATE_EPOCH
exists, we assume that a reproducible build is intended and the
"Linux-6.1.0-23-amd64" string is replaced with "-" (hyphen).
