Candidate for PR/13485 Generated files no longer get messages extracted

[Kelley Cook <kcook34 at ford dot com>]

This is a floater for fixing PR/13485.

First off, it does not do all the nice things that Joseph would like for 
this patch to do, but it does appear to fix the regression with the 
minimal impact required for stage 3 fix.

Quite simply the po.generated target is nuked and replaced with srcextra 
which already lists all of the generated files.  All that was required 
in order for this to work I had to add in a layer of indirection to the 
srcextra target in gcc/Makefile.in, which likely should be done anyway.

It also fixes a bug I came across by adding in the required dependency 
on options.c to po/${PACKAGE}/gcc.pot.

The only slight flaw I see is that make po/gcc.pot would be required to 
be run in a read-write source directory, but that stipulation could just 
be added to the as of yet non-existant documentation that the source 
directory must remain read-only except in the current cases of 
--enable-maintainer-mode and --enable-generated-files-in-srcdir.

tested with:
configure --enable-languages=all,treelang
make configure-gcc
cd gcc
make po/gcc.pot

OK?
