Build problems after r19920

[Mike Alexander]

SVN version r19920 introduced a couple of build problems.  This changed 
made src/core-utils/gnc-main.c include "gnome-utils/gnc-version.h". 
This works only if the build directory is the source directory.  I 
normally build in a separate build directory parallel to the source 
directory.  That way I can have both a debug and optimized build and I 
can start over from scratch by just blowing away the build directory 
(or moving it aside).

This problem can be fixed by changing the include to just 
"gnc-version.h" and adding -I${top_builddir}/src/gnome-utils to 
AM_CPPFLAGS in core-utils/Makefile.am, but then you hit another problem 
that I'm not sure how to fix.  The problem is that gnc-version.h is 
built by gnome-utils/Makefile.am, but core-utils is built before 
gnome-utils.  This means that if you build from scratch gnc-main.c 
tries to include it before it exists.

Something needs to get rearranged.  You can't really move 
gnc_get_svn_version to gnome-utils since it needs to be available in a 
non-GUI build.  I don't know what would happen if you tried to build 
gnome-utils before core-utils, but I suspect it wouldn't work.
