In the first case, it doesn't matter. In the second case, we would have to 
run benchmarks where one build uses --with-pic and not the other. The PIC 
library is a tiny bit larger (1321280 vs 1319632). GMPbench doesn't really 
see the difference on x86_64 core2 (2117 vs 2124), but it may not be the 
best test for this.
