[PATCH V4] RISC-V: Fix a redefinition bug for the fd-4.c

[shiyulong]

From: yulong <shiyulong@iscas.ac.cn>

This patch fix a redefinition bug.
There are have a definition about mode_t in the fd-4.c, but it duplicates the definition in types.h that be included by stdio.h.

gcc/testsuite/ChangeLog:

        * gcc.dg/analyzer/fd-4.c: delete the definition of mode_t.

[PATCH V2] RISC-V: Modified validation information for contracts-tmpl-spec2.C

[shiyulong]

From: yulong <shiyulong@iscas.ac.cn>

This patch fixes the problem of the contracts-tmpl-spec2.c running failure.
When run the dejagnu test, I find that the output is inconsistent with that verified
in the testcase. So I try to modify it, and then it can be passed.

I think you need to debug why you get different output from this test. 
Just removing the output because it didn't match on risc-v seems wrong.

This may not be advisable.  I wouldn't be shocked to find out there are 
systems that do not provide mode_t.

Ultimately David Malcolm (on cc) should make the final decision here. 
It's really not a RISC-V problem.
