If you match the exact build-deps I use and the exact options from
debian/rules you should end up with the exact same output. As that is whay
you desire but do not get we need to drill down into where it deviates. FWIW
last time I build the Debian the (relevant) part (of the large) configure log
was below. What do you get for BLAS/LAPACK?

the /etc/alternatives mechanism you are after. (That was from rocker/r-base,
a quick way for me to get to clean and current Debian build.)
