RE: [PATCH] RISC-V: Enable static-pie.

["Wang, Yanzhang" <yanzhang.wang@intel.com>]

I took some time to test the master with binfmt_misc and qemu system mode.
Both of them can't match the requirements (<= 6 failures).

- most of cases with binfmt_misc fail with abort.
- most of cases with qemu system fail with timed out.

And also tested with my risc-v board and still fails 70+ cases and most of
them are math accuracy issue.

So Adhemerval, do you know how to setup the environment to reproduce
the <= 6 failures ? Maybe I lost some important steps. Thanks very much :).

Thanks,
Yanzhang
