perf_3.4.bb: update to build against older kernels
Removes a make install-python_ext when not present since
older versions of perf lack this install rule
This also fixes a library issue on older kernels building with
a newer toolchain where libaries that would previously be pulled
in are no longer. So we add them manually.
