when preprocessing a .S file, unknown directives should just be passed through,
and the token after the # should be expanded if it is not a valid directive.
This allows us to transform things like:

#define FOO BAR
# FOO

into # BAR, even though FOO is not normally expanded for directives.

This should fix PR3833
