tinderboxes please upgrade bison

[Lionel Elie Mamane]

Hi,

My commit
http://cgit.freedesktop.org/libreoffice/core/commit/?id=f220c3913a167b0d9702aca2b623839abe8665f1
broke some tinderboxes, but not others. I suspect that's because of
older version of bison on these tinderboxes.

What bison version do
 Linux-x86_64_32-callgrind
 MacOSX-10.8 at 21-10.7SDK
have, and could you please upgrade it?

Someone would have an idea what version of bison our configure.ac
should now require?
