9.3.0: increase expmed cache size from 10^3 to 10^6
Without this patch is takes dev-libs/xxhash 1-2 hours
to compile. With this patch - TODO measurements.
It workarounds deficiency of synth_mult() which evics
cache entries as it calculates optimal multiplication
algorithm. xxhash is especially hevyweight as it's a
64-bit multiplication of large prime constants.
