./gcc/xgcc -print-multi-directory -march=rv32imafd -mabi=ilp32d
rv32imafd/ilp32d
---------------------------
The difference is rv32imafd/ilp32d is disappeared from the output of
-print-multi-directory, the gcc think that could reuse the default library, but
it's not true, but seems like -print-multi-directory is doing right here.
