--whole-archive support

    A patch is implemented as suggested in tinycc-devel mail list.

    Subject: [PATCH] Add --{no,}-whole-archive support

    I resurrected the patch supplied to the mailing list in 2009
    Since --whole-archive is a useful flag to get tcc working with
    autotools, and of course in its own right, I suggest you have a look
    at the patch and see if it is acceptable. I cannot see any suggestion
    that it was actively rejected last time round, just no evidence that
    it was ever added.
