-This patch removes the code that tries to figure out the cache size of
-the host. The algorithm may very well fail under some circumstances --
-it makes too many assumptions about the cache behaviour, but most
-importantly, the figured out values ARE NOT USED anywhere in the
-ghostscript code anymore.
