There are a number of scripts in the perf installation that use bash,
so we need to add a run-time dependency on bash for them. If not, we
can generate build errors like "no package provides /bin/bash".

Fixes [YOCTO #3951].

perf depends on bison and flex for event parsing - add them as
dependencies.

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.

Add a new feature named 'perf-tui'.  Adding this into the
PERF_FEATURES variable in perf.inc will enable the perf TUI (Text-base
UI) user interface on a target, which adds libnewt and turns on the
perf text UI options in perf, if perf is included in an image.

If 'perf-tui' isn't named as a feature (the default), the perf TUI
will be disabled and unavailable.

Add a new feature named 'perf-scripting'.  Adding this into the
PERF_FEATURES variable in perf.inc will enable perf scripting on a
target, which will turn on all the language bindings currently
available in perf (Perl and Python), if perf is included in an image.

If 'perf-scripting' isn't named as a feature (the default), all perf
language bindings will be disabled and unavailable.

This shouldn't be unconditional - a later patch made it so, but that's
not yet pulled in.  In the meantime, to fix build failures remove the
unconditional install.
