Hi,
With commit 07667c911b1 ("[nvptx] Build libraries with misa=sm_30") the
intention was that the sm_xx for all libraries was switched back to sm_30
using MULTILIB_EXTRA_OPTS, without changing the default sm_35.
Testing on an sm_30 board revealed that still some libs were build with sm_35,
so fix this by switching back to default sm_30.
Tested on nvptx.
Committed to trunk.
Thanks,
- Tom
