The SOURCE_DATE_EPOCH mechanism for reproducible builds requires the GNU
variant of date.
Why does it require the GNU date ?
Cause of the -d switch. It is used in GNU date variants to set the time
to print the string from. On the other hand *BSD variants use it to set
the DST flag.
This sort of stuff should be in the commit message :)
Respect this and search it, error on missing GNU date.
Wouldn't it make more sense to fix the code to NOT depend on GNU
extensions ?
That would be great, but so we need to check for the tool and use the
right switches depending on that.
I think forcing the user to provide the right tool here is Ok.
I think we don't have a better option here anyway, right ? Maybe try
checking uname ? But you can have linux with bsd userspace ... and
probably BSD with GNU userspace, meh.
