There's been a long-standing bug in the arm backend where
target-specific directives did not correctly handle lines with
multiple statements. This patch fixes the issue for all the cases
I've been able to find.
It does result in a slight change in behaviour when errors are
encountered: where, previously,
.cpu arm6 bar
would result in the error "junk at end of line, first unrecognized
character is `b'", we now get "unknown cpu `arm6 bar'", which I think
is slightly more helpful anyway. Similar errors are generated for
other directives.
