Description
I attempted to build a PPC64 version of FFMPEG, and when the build system trys to ld ffprobe_g, it returns an error:
/usr/bin/ld: libavcodec/libavcodec.a(iff.o)(.text.unlikely+0x188): sibling call optimization to .opd' does not allow automatic multiple TOCs; recompile with -mminimal-toc or -fno-optimize-sibling-calls, or make .opd' extern
/usr/bin/ld: final link failed: Bad value
collect2: ld returned 1 exit status
The configure command I used is as follows:
./configure --enable-gpl --enable-version3 --enable-nonfree --enable-libx264 --extra-cflags="-m64 -mcpu=G5 -mtune=G5 -mpowerpc64 -maltivec -fno-optimize-sibling-calls" --extra-cxxflags="-m64 -mcpu=G5 -mtune=G5 -mpowerpc64 -maltivec -fno-optimize-sibling-calls" --extra-ldflags="-m64 -mcpu=G5 -mtune=G5 -mpowerpc64 -maltivec -fno-optimize-sibling-calls"
I already built a 64bit version of libx264 to build against.
I checked the version of FFMPEG that built in the directory, and it exectutes and is a 64bit executable. A test encode shows that it's about twice as fast as a 32bit build (using command ./ffmpeg -i ~/Desktop/file.mpg -vcodec libx264 -preset medium -crf 16 -acodec copy ~/Desktop/file.mkv) I get around 20fps vs. 9fps on a 32bit build.

btw if someone knows where i can find a cross compiler for ppc64 (some debian or ubuntu package ideally) or some simple description of how to build one then this should be easy to resolve.

Also as theres no reply to my questions from 3 month ago this bug is not important. evidently noone cares enough to awnser them so i downgrade to normal priority

I just tested compilation on a Linux PPC64 server and it succeeds (including fate).
googling for this error message points to a gnu ld bug. I dont know if this issue here is caused by that bug or not but if you can , please try a different compiler and or different linker. (especially one that is known to have this bug fixed) Also please tell us the exact versions of the tools used to build
