Elliot and I had some discussions recently where we were thinking it might be a good idea to combine some of these settings under one easy group flag like JULIA_PORTABLE=1 or something, that would then set OPENBLAS_DYNAMIC_ARCH, along with the flags needed for the system image that I can never remember. If we get that working and documented, then we could consider disabling OPENBLAS_DYNAMIC_ARCH by default so we can have faster from-scratch source builds.
