[Libreoffice] please pick those two build-related commits for libreoffice-3.5 (XCode 2.5 build breaker & download → use same branch for the clones)

[Christian Lohmaier]

Hi *,

please pick http://cgit.freedesktop.org/libreoffice/core/commit/?id=9a845f988e6b5ec50ddda123cf761d8541c005fa
(change to download, so that when using linked git repos,
git-new-workdir will checkout the same branch as the core repo)
and
http://cgit.freedesktop.org/libreoffice/core/commit/?id=f56780576fa8c28cd212ddfffc554cee40698009
(build fix for Mac OSX 10.4 / XCode 2.5 where -dead_strip_dylibs is
not supported - the makefile in libreoffice-3.5 uses .IF .ELSE
construct instead of $(eq,...), but the idea is the same, just remove
the flag - on Mac there is not much cruft linked to begin with)

ciao
Christian
