[pcre-dev] [PATCH] Generating config.h.generic

This is a small patch that I've been sitting on for some time. It moves
the generation of config.h.generic from the PrepareRelease script to
Makefile.am, for consistency with the existing pcre.h.generic rule. Also,
it adds a missing backslash to PrepareRelease.

(Note that PrepareRelease no longer has anything to do with respect to
these files, because with this patch, both are generated automatically in
the course of a "make dist".)
