Excessive two spaces.

This will create file in current directory, that should not happen.  Please
use ${objdir}/${subdir} and also ${testfile} prefix, something like:
set tempfile ${objdir}/${subdir}/${testfile}.x

$tempfile should be deleted first as otherwise it may create false PASSes.

Optional - not required but I would find better: You could use TCL `file
exists' and `file delete' instead of making some more dependencies on host
shell compatibility.  You could also check the content of such file, whether
the redirection was successful, lib/gdb.exp build_id_debug_filename_get
contains reading of a file by TCL.
