[OpenJDK 2D-Dev] jdk-hs ppc64le build error, probably related to libpng update

Hi Phil, it looks like  the recent  png lib change

8183960: Upgrade to libpng 1.6.34


+#  define PNG_FILTER_OPTIMIZATIONS png_init_filter_functions_vsx

Causes  build errors  in  our  linuxppc64le   openjdk  jdk-hs (fast)dbg  build .

We get  this linker error :

pngrutil.c:(.text+0x4824): undefined reference to `png_init_filter_functions_vsx'

Do  you  have  a version of libpng  available that  contains  the missing function  png_init_filter_functions_vsx  ?
Or do you have an idea where it should come from (I cannot find it in the main libpng sources).

To fix the build, we could probably disable  the part  bringing in png_init_filter_functions_vsx   in png_init_filter_functions_vsx  .

Thanks, Matthias
