[testsuite] [vxworks] tolerate missing __atomic_feraiseexcept
vxworks' libatomic comes from its libc, and it's missing
__atomic_feraiseexcept. ARM and AArch64 ports call it implicitly in
c11-atomic-exec-[23].c, so these tests fail.
No exceptions are expected to be raised by these tests, so I'm working
around and silencing the failures by defining the missing function
when compiling for the affected target.

* gcc.dg/atomic/c11-atomic-exec-2.c [__VXWORKS__]
(__atomic_feraiseexcept): Define.
* gcc.dg/atomic/c11-atomic-exec-3.c: Likewise.
