Description: Makefile: use fixed build host if SOURCE_DATE_EPOCH is defined
If SOURCE_DATE_EPOCH is defined then we can be reasonably sure the
user wants the build to be fully reproducible, so use a fixed string.
In case of a cross build, using uname -s -m -p -i o will still report
the host's kernel architecture, which will trip some CIs like
Debian's.
