  Hi,

In gcc-11, when  specifying -misa=sm_30, an executable may still contain sm_35
code (due to libraries being built with the default -misa=sm_35), so it won't
run on an sm_30 board.

Fix this by building libraries with sm_30, as was the case in gcc-5 to gcc-10.

Committed to trunk.

Thanks,
- Tom
