Subject: [PATCH] flag-o-matic.eclass: filter out '-B/foo' and '-B /foo'
 equally
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

In bug #687198 Julian noticed that strip-unsupported-flags()
filters out '-B' but not '/foo' in CFLAGS='-B /foo' and causes
breakage.

This change still does not allow -B flag but at least filters
out both '-B' and it's parameter.
