Performance analysis tools for Linux

Build perf with DWARF unwinding support. Kernels older then 3.14
need to be patched to add ARM support. Kernels for tibidabo (3.0)
and imx53 (2.6) are too old and would require more patches to be
backported, so they are left without unwinding support.

RPi needed extra layer to modify the kernel recipe, and linux-imx
recipe was renamed so that it doesn't conflict with older tibidabo
kernel recipe.
