Remove testsuite compile errors with GCC5.

GCC5 defaults to the GNU11 standard for C and warns by default for
implicit function declarations and implicit return types.
https://gcc.gnu.org/gcc-5/porting_to.html

Fixing these issues in the testsuite turns 9 untested and 17 unsupported
testcases into 417 new passes when compiling with GCC5.

gdb/testsuite/ChangeLog:

        * gdb.arch/i386-bp_permanent.c (standard): New declaration.
