Presumably you meant "tar implementations" and not "make
implementations"? But this is already the case, as the existing code
uses the -o option, which is specific to GNU tar (the -o option has a
different meaning with traditional tar, and traditional tar rejects -o
when creating archives).

True: any such patch along these lines would have to configure this,
depending on whether "tar" supported the option in question. Come to
think of it, while you're at it you could also see whether -o is
supported, so that the makefile ports to non-GNU tar implementations.

Quite true. Few implementations support the POSIX 1003.1-2001 format.

Yes, I think this is the best approach: that is, use --format=ustar if
available, then -o if that works, otherwise don't use anything.

That also might be helpful, though I think not as useful; most users
won't want to futz with this.
