[PATCH OBV] Add nowarnings in gdb.base/fileio.exp

[Yao Qi <qiyaoltc@gmail.com>]

I see the following warning in gdb.base/fileio.c,

testsuite/gdb.base/fileio.c:297:3: warning: null argument where non-null required (argument 1) [-Wnonnull]
   ret = stat (NULL, &st);
   ^

This patch adds "nowarnings" to the list passed to gdb_compile.

It is obvious, patch is pushed in.
