[REVIEW][3-5] fdo#42865, SVN 1.7, etc.

[Michael Stahl]

so today i had the glorious idea to do a build on new-fangled not-even
-released-yet Fedora 17 of the libreoffice-3-5 branch with my usual
settings.  unfortunately those include -Werror, and if i had known how
many of these turn up with the new gcc 4.7 i would have disabled that
instead of backporting 30 or so patches, but now it is too late :)

on top of that i propose the following for libreoffice-3-5:

* SVN 1.7 breaks python build:
http://cgit.freedesktop.org/libreoffice/core/commit/?id=7e5a6a385051569da1bf872989aef262f2d802e2

* fdo#42865 the --enable-dbgutil only problem of _GLIBCXX_DEBUG adding a
new symbol with unique linkage has re-surfaced and spread further, most
likely due to the new std::string based SAL_LOG stuff; strangely it
seems to work on Fedora 16 but on 17 it crashes and burns immediately in
sal unit tests; attached patch fixes it for -3-5 (the Conflicts are all
the gbuild converted libs on master, on -3-5 it is sufficient to fix the
addsym.awk)

* disable -Wno-deprecated-declarations because nobody cares on the
release branch (kind of silly but prevents the only warnings still left
for me), see attachment.
