Yes, I wanted to put each argument in quotes.

They are expanded once by Make, and then again by the shell inside
double-quotes.

I'm afraid I didn't get a copy of the patch, could you send it to me
privately?

I'm not sure that's quite enough of a pathological test case.  Try
adding --manpath=$(prefix)/share/man or --manpath=${prefix}/share/man ...
