openblas

(CCing the R-devel list, maybe someone will have a better answer.)

To be honest, I don't know how to. I wasn't able to configure R to use
OpenBLAS using the configure script and options on my Linux Fedora system.
I configure it without external BLAS, then replace the libRblas.dylib (.so
in my case) with a link to the OpenBLAS dynamic link library.

R on Fedora uses openblas by default since Fedora 23. In fact, there's
a specific package, openblas-Rblas, that provides libRblas.so.

$ ll /usr/lib64/R/lib/
total 64544
-rwxr-xr-x. 1 root root 60113776 feb 28 13:37 libRblas.so
-rwxr-xr-x. 1 root root  1961880 mar 11 20:37 libRlapack.so
-rwxr-xr-x. 1 root root   182304 mar 11 20:37 libRrefblas.so
-rwxr-xr-x. 1 root root  3828104 mar 11 20:37 libR.so

R reference blas is installed as libRrefblas.so.
