I suggest that you mark this one as "Legacy" rather than take it out.

Nearly all of the Media Player manufacturers are using a SoC vendor
provided toolchain based on 3.4.4 -
Even brand new designs, announced within the past few months!
(yeah, and they are running kernel 2.6.12.6 but NABRP)
((Not A BuildRoot Problem))

Due to compiler ABI changes, we still need 3.4.x for add-in software.
