Change filesystem buffer cache size calculation to be less for 4MB
machines (now 20% of all memory after the first 3MB). This is necessary
in order for 4MB machine to be able to rebuild the entire source tree
and not run out of physical memory because of fixed memory requirements
of processes and kernel VM.
