[sane-devel] Please clean before CVS update

[Chris Bagwell]

Thanks for the report.  I should have also mentioned that part as a 
warning.  I modified backend/Makefile to only link in what it needs.  On 
my platform, coolscan2 didn't need math for some reason.

I'll submit the fix in a minute but if others have similar issues, here 
is a list of items that you can add to the specific 
"libsane_$(BACKEND_NAME)_la_LIBADD" line and it will get 
auto-substituted by configure; generally only when a platform needs it.  
Please bare with me as these failure occur on platforms I do not have 
access to.
