Use fallback libraries for archs without optimized logic (ROCm#1862)

Fixes ROCm#1757. Enables architectures that don't have optimized logic files to also produce libraries when `--separate-architectures` or `--lazy-library-loading` is turned on. Previously, one must disable both of these two flags in order for rocBLAS to run on architectures like `gfx1010`.
