Your first snippet shows:

>>> /usr/local/lib64/libx265.a(bitcost.cpp.o):

That means you are trying to compile with static libx265.a; the default
seems to be shared libx265.so. Do you know how you achieved this? Maybe

This happens even if -DENABLE_SHARED=OFF was set, and I believe this is
wrong. Compare with what x264 produces:

* With --enable-shared:

  Libs: -L${exec_prefix}/lib -lx264 
  Libs.private: -lpthread -lm -ldl

* With --enable-static:

  Libs: -L${exec_prefix}/lib -lx264 -lpthread -lm -ldl

So my diagnosis is that x265's .pc file is wrong when x265 is built with
shared libraries disabled.
