[committed] Fix minor testsuite problems on H8 after C99 changes

[Jeff Law]

Two minor regressions on the H8 were triggered by the C99 changes. 
First pr58400.c has several functions without prototypes.  I just added 
-fpermissive to that test.  Second pr17306-2.c has a single call to an 
unprototyped function for which I added the prototype.

These are both H8 specific tests.
Pushed to the trunk,
