winegcc: add support for -B prefix

[Dimitrie O. Paun]

Never used -B before, so I don't know if this is how it's
supposed to behave. Basically, if a prefix is given, I first
look there for the name of the executable. If I find a
file that's executable, I run that. If not, I default to
the original.

ChangeLog
    Dimitrie O. Paun <dpaun at rogers.com>
    Add -B prefix support. Small consistency cleanups.
