Note that this test is meant to test remote file io capabilities.
The fact that it runs on a native gdb is merely a way to give it
a bit more exposure against bitrot.  We need to make sure to not
simply fail the test if the syscalls we're introducing are not supported
by remote file io (remote-fileio.c), and they fail on the
target (e.g., ENOSYS), and also that the test still compiles on
bare metal targets, with e.g., newlib (otherwise, the test becomes
useless).  (The test was probably running on Windows/mingw as well,
but the "geteuid" call introduction is probably making it not compile
there anymore.)
