The patch apparently works around a problem where Automake doesn't AC_SUBST for 
mkdir_p. There was some talk of Automake removing support for mkdir_p (it's 
still listed as deprecated in the man page). Perhaps Debian Automake removed 
mkdir_p support at some point, and then reverted the removal? That would explain 
why you don't need the patch any more.
