Makefile syntax is documented at
http://pubs.opengroup.org/onlinepubs/9699919799/utilities/make.html#tag_20_76_13_03

This just suppresses the behavior of "if this command fails, immediately
exit 1 instead of trying to do anything else".

It's a fancy way of doing `|| true`.

The obvious question would be... since makepkg (not makechrootpkg) told
you that that directory is not a clone of that url, then what is it a
clone of instead?

I'm not sure how much clearer we could make that error message. If
there's something makepkg is doing dreadfully wrong in that error
message reporting, please tell us so we can fix it...

It's not odd at all, unless you missed my post shortly before yours. :)

I'm blindly assuming this was intended to be "a post-install script to
fix it", but even then no, plus it wouldn't really get rid of the errors.
