Revert "Let's try gcc with -march=haswell"

This reverts commit 07fd3bac2529867a46d9dd610ca4dfaedeb20172.

Update value for (acosh 4d0) for core-math

Core-math returns 2.0634370688955603d0.
I'm going to assume that's correct even though (acosh 4w0) is
2.06343706889556054672728117262013w0

And Maxima says:
2.063437068895560546727281172620131871456591449883392499836032693b0
