Are you using ppc64 or ppc64el? This package you listed should be used if you
are cross compiling, which does not seem to be the case.

This package seems to come from GCC, where it is compiled with the following
flag:

  --disable-libquadmath   do not build libquadmath directory

I am wondering if the toolchain was compiled using this flag somehow.
