[REVIEW][3-5] use system stdlibs on Linux by default (fdo#45074, fdo#45696)

[Petr Mladek]

Hi,

the bundled stdlibs caused problems with 3rd-party extensions and
exceptions handling. It was decided on the last TSC call to use system
stdlibs for Linux bugs, see
http://lists.freedesktop.org/archives/libreoffice/2012-February/025670.html

I did this change in master, see
http://cgit.freedesktop.org/libreoffice/core/commit/?id=0787025c13dadd6e8e131cb491698e6981313c4a
http://cgit.freedesktop.org/libreoffice/core/commit/?id=739100d0abcf6025835028b9d503bf3e11cd77db

Could you please approve them for 3-5 branch?
The attached patch merges the two commits into one.


Best Regards,
Petr
