Bug#386815: gtk+2.0: FTBFS (ppc64): sibling call optimization to `IA__gdk_display_open' does not allow automatic multiple TOCs; recompile with -mminimal-toc or -fno-optimize-sibling-calls

Hello,

thanks for looking at the ppc64 related bug.

Yes, a patch adding the -mminimal-toc flag to CFLAGS is still necessary 
on ppc64. I will attach an updated version of the patch which applies
to the latest version in unstable (2.10.13-1).

I am not aware of any newer binutils version which would make it 
possible to build gtk+2.0 without the extra -mminimal-toc flag on ppc64.
