If there is no matching BSP, then you get nothing. I think this is the 
right thing to do. Doing a

./waf bsp_defaults --rtems-bsps=riscv/rv64imac_medany  > bsps.ini

is not a recommended use case. You should only set the necessary minimum 
of options.

Yes, this is currently the intentional behaviour. Should this be changed to

conf.find_program(XYZ, path_list=tools + 
environ.get('PATH','').split(os.pathsep))

?

Yes, this is work in progress. I should work now.

Ok, this is a bug, you should find the samples.

You have to set the compiler in the config.ini file, see latest user 
documentation:
