It's debatable wheather sane-config should find any other 
sane-backends.pc than the cleanly make installed one.

If this would be wanted we could do only
export PKG_CONFIG_PATH="@libdir@/pkgconfig"
without touching PKG_CONFIG_LIBDIR.

But IMO that use case is already covered by directly using pkg-config.
The way I did it here we can be more sure to include/link against that 
sane-backends the called sane-config belongs to.

Also it's IMO worth to think about declaring sane-config deprecated to 
remove it completely in some years.
