Use of `abs` in the pivoting branch of the generic lufact.

[mschauer]

The use of abs in the pivoting part broke some code of mine which was using the generic lu-fact on a matrix with elements of type SArray{Tuple{2,2},Float64,2,4}. This became visible with the change JuliaLang/julia#32989 making pivoting the default. Would norm be an option there?

Would norm be an option there?

I'd think so.

This should be open again, as JuliaLang/julia#34575 wasn't the solution.
