Why is Guile now setting LD_LIBRARY_PATH?

I added a couple of debug printf's after several hours chasing down
why my program was crashing:

> in main() LD_LIBRARY_PATH='EMPTY'
> in inner_main() LD_LIBRARY_PATH='/usr/lib64:/usr/lib64/guile/2.0/extensions'

It was crashing because it was linking against a library in /usr/lib64
instead of /usr/local/lib64.  Now I know why.

1.  Why was this done?
2.  Why no notice?  This is *BROKEN*.

libguile needs to be linked with -Wl,-rpath -Wl,/usr/lib64/guile/2.0/extensions
instead of messing up your client's link/load.  ("/usr/lib64" should not be 
needed.)

Distribution:  openSuSE 12.2  (Just in case they are not following your
build procedures and I need to harass them.)
