[Libreoffice] Relaxed ccache acceptance for Mac (was: [Libreoffice-commits] .: Branch 'libreoffice-3-4' - configure.in

[Thorsten Behrens]

FYI - it seems ccache has all the issues fixed in 3.1, that were
mentioned in http://openoffice.org/bugzilla/show_bug.cgi?id=104567,
so I bulk-accept versions greater or equal now.

    Auto-accept ccache >= 3.1 on Mac
    
    The reason for the selective rejection of everything but a patched
    ccache on Mac was broken objective-c/c++ support and a memory
    corruption on arg parse - both are fixed on 3.0 and 3.1,
    respectively. See http://ccache.samba.org/releasenotes.html
