I give you that we should properly document what GLOB_ALTDIRFUNC
expects for partially initialized glob_t alternative functions, but currenyl
glob code assumes that if GLOB_ALTDIRFUNC is set then glob_t
function pointers actually points to valid implementation.

So I think this is essentially a make issue. And since make also packs
its own glob copy from gnulib, it is matter to fix on make if and when
it syncs with gnulib.
