[PyPy-issue] [issue546] classes in translator.platform should use tuples in the class attributes

[Amaury Forgeot d Arc]

New submission from Amaury Forgeot d Arc <amauryfa at gmail.com>:

in the code of pypy/translator/platform/*.py, it's too easy to forget that some 
attributes are 
lists, stored in the class dict:

flags = self.link_flags    # a class attribute, Linux.link_flags
flags += ['-g']            # updates Linux.link_flags!

of course one should write "flags = self.link_flags[:]", but it would be safer 
to turn them 
into tuples, which are not mutables.
