This smaller difference might be due to mold.

Using mold and building with -g1 might get the build time under 1 day 
(untested), but even 52 hours is still less than the runtime of the 
testsuite of gcc (whose results are ignored) - and is in general not 
extraordinarily long.

I'm not saying this is good, but with the current buildds 11 days was 
too much but 2 days is OKish.
