gl_GLOB_SUBSTITUTE

[Bruno Haible]

Hi Paul, all,

When the 'glob' module was created in May 2005, a macro gl_GLOB_SUBSTITUTE was
introduced. It is now unused (nothing in gnulib nor in other packages uses it).
Derek Price's rationale was [1]
  "gl_GLOB_SUBSTITUTE can enable the glob module without a call to
   gl_GLOB at all"

Basically its effect is to use the included glob sources even on glibc
systems. But what's the point, given that the gl_GLOB macro does the
replacement more carefully?

I propose to remove this macro.

Bruno
