Add another layer of indirection to get @bindir@ and friends in the output. When we create php.eselect from php.eselect.in using autoconf, we don't have a way to get the full, expanded value of @bindir@, @libdir@, and the other paths that we need. The autoconf documentation suggests a workaround for this: add another layer of indirection, and use the Makefile to substitute those values into the output files. This commit sets the stage by renaming php.eselect.in to php.eselect.in.in. The first round of processing by autoconf takes php.eselect.in.in to php.eselect.in. The Makefile will then generate php.eselect from php.eselect.in after substituting @bindir@, @libdir@, and @localstatedir@.
